[Copied to Feature Requests thread here.]

Yes. This is a known issue and a bug report has already been logged with the developers.
It should be resolved in the next version (although I do not know when this will be released).

For anyone reading this thread, this problem happens only when using web mail (e.g. Gmail).
There is no problem when using an email client program such as Outlook or Thunderbird.

If you still see the Juicebox logo in the lower right corner, then the gallery is still Juicebox-Lite.
The Juicebox logo is present in all Lite galleries but not in any Pro galleries.

First of all, please try completely clearing your browser's cache before reloading your gallery's web page to see if the problem is a browser caching issue. (Your browser might be storing and using the Lite files.)

If this does not clear the problem, then please try the Upgrading to Juicebox-Pro instructions again but, this time, try deleting the Lite 'jbcore' folder from your web server first before uploading the Pro version in its place.

Please note that upgrading WP-Juicebox to Juicebox-Pro does not change the plugin's interface.
Only Lite options will have their own individual controls but all Pro options entered in the Pro Options text area will become active.

I hope this helps.

When you create a gallery with JuiceboxBuilder-Pro, the application stores the locations of the source images in the gallery's 'config.xml' file (the sourcePath attributes in the <image> tags).
As long as you do not relocate your source images, JuiceboxBuilder-Pro will use the un-watermarked source images (rather than the already watermarked gallery images) if a new watermark is to be applied to the images (so gallery images will not be watermarked twice).

If the source images are no longer available in their original locations, then JuiceboxBuilder-Pro will have no option but to use the already watermarked gallery images and will watermark them again.
In this case, the best course of action would be to copy the gallery images to a safe location whilst the gallery is being saved and then move them back into the 'images' folder afterwards (overwriting the double-watermarked images).
The image filenames will be the same so there will be no need to modify any paths in any files.

I hope this helps.

There are many ways that you can structure your web site and Juicebox galleries.
Here are a few tips which might help.

Using the regular embedding code noted here (and presented on the 'Publish' tab of JuiceboxBuilder-Pro), the contents of the gallery folder (not the gallery folder itself) should be uploaded to the same directory as the web page containing the gallery's embedding code.

If you move of rename the gallery's configuration file (default name 'config.xml'), then you can point towards it using a configUrl entry within the gallery's embedding code, for example:

<!--START JUICEBOX EMBED-->
<script src="jbcore/juicebox.js"></script>
<script>
    new juicebox({
        configUrl: "folder_1/folder_2/configuration_file.xml",
        containerId: "juicebox-container",
        galleryWidth: "100%",
        galleryHeight: "100%",
        backgroundColor: "#222222"
    });
</script>
<div id="juicebox-container"></div>
<!--END JUICEBOX EMBED-->

No matter whether of not you use a custom configUrl, all relative paths within the gallery's configuration file ( imageURLs, thumbURLs and linkURLs) will be relative to the web page containing the gallery's embedding code.

Short descriptions of the configUrl and baseUrl embed options can be found here.

Alternatively, you could upload a complete gallery folder to anywhere on your web server and point towards it using a baseUrl entry within the gallery's embedding code, for example:

<!--START JUICEBOX EMBED-->
<script src="folder_1/folder_2/gallery_folder/jbcore/juicebox.js"></script>
<script>
    new juicebox({
        baseUrl: "folder_1/folder_2/gallery_folder/",
        containerId: "juicebox-container",
        galleryWidth: "100%",
        galleryHeight: "100%",
        backgroundColor: "#222222"
    });
</script>
<div id="juicebox-container"></div>
<!--END JUICEBOX EMBED-->

The baseUrl method of embedding is documented here.
When using the baseUrl method of embedding, all relative paths within the configuration file (imageURLs, thumbURLs and linkURLs) will be relative to the baseUrl.

Additionally, you can upload your gallery's 'jbcore' folder to anywhere you like on your web server. In fact, multiple galleries can even share a single 'jbcore' folder. Please see here for details.
All you need to do is make sure that you point towards the 'juicebox.js' file within the 'jbcore' folder within the <script> tag, for example:

<!--START JUICEBOX EMBED-->
<script src="folder_1/folder_2/jbcore/juicebox.js"></script>
<script>
    new juicebox({
        containerId: "juicebox-container",
        galleryWidth: "100%",
        galleryHeight: "100%",
        backgroundColor: "#222222"
    });
</script>
<div id="juicebox-container"></div>
<!--END JUICEBOX EMBED-->

The location of the 'jbcore' folder is completely independent of the configUrl and baseUrl options (which still work as noted above).

if you use any of the suggestions above, then you will not need to modify any of the paths inside the gallery's configuration file.
However, if you want to store your images elsewhere on your web server (not inside the 'images' and 'thumbs' folders within the gallery folder), then you will need to manually modify the paths (the imageURLs, thumbURLs and linkURLs) inside the gallery's configuration file (by opening the file in a plain text editor) bearing in mind that if you use a baseUrl, then relative paths will be relative to the baseUrl.

I hope this helps.

That's great to hear. Thank you for letting me know.

As you have discovered, you need to update the plugin first (as it comes bundled with Juicebox-Lite). Afterwards, you can upgrade the plugin to use your Juicebox-Pro files.

No. The TinyMCE editor was never included within WP-Juicebox.
Older versions of the plugin included code (inside a folder named 'tinymce') to add an 'Add Juicebox Gallery' button to WordPress's own TinyMCE editor toolbar.
However, later versions of the plugin moved the 'Add Juicebox Gallery' button from the TinyMCE editor toolbar to alongside WordPress's 'Add Media' button (and so the TinyMCE code was no longer required and the 'tinymce' folder was removed from the plugin package).

I have run the current version of WP-Juicebox (v1.5.1) under PHP 7, 7.1, 7.2 and 7.3 without any problems but if you find any issue with WP-Juicebox under a certain version of PHP, please let me know so that I can investigate further. Thank you.

Please see this FAQ regarding the 'Config file not found.' message:
When I view my gallery I see the message 'Config file not found'. How do I fix this?

If you encounter this message, then the gallery's configuration file is likely to be in the wrong location.
By default, the gallery's configuration file should be named 'config.xml' and should be located in the same directory as the web page containing the gallery's embedding code.

If you rename or relocate the gallery's configuration file, then you can point towards it with a configUrl entry in your gallery's embedding code.
The configUrl entry can be an absolute path (in the form http://www.example.com/gallery/custom.xml) or a relative path (relative to the web page containing the gallery's embedding code).

Also, if you use a baseUrl entry in your gallery's embedding code (to point towards a gallery folder), then a relative configUrl will be relative to the baseUrl.

Short descriptions of all the Embed Options (such as configUrl and baseUrl) can be found here.

Another possible reason for encountering the 'Config file not found.' message would be if the configuration file is somehow corrupt or incomplete.
Open your gallery's 'config.xml' file directly in a browser and the browser should let you know if there are any syntax errors in the code (which you can then correct).

If you encounter the exact text 'Config XML file not found.', then you are using an older version of Juicebox.
In v1.5.0 (released on 24 May 2016), Juicebox first supported JSON configuration files as well as XML configuration files and the error message was changed from 'Config XML file not found.' to 'Config file not found.'.
I'd recommend that you upgrade your Juicebox gallery to the latest version (v1.5.1) to ensure that any bugs from previous versions (which have since been fixed) are not contributing to your problem.
For reference, full instructions for Upgrading Juicebox can be found here.

I hope my notes above help.
However, if you continue to experience difficulties, then please post the URL to your gallery's web page so that I can see the problem for myself and hopefully help further.
Thank you.

Sorry, my last post was incorrect.
In Small Screen Mode, captionPosition uses the value OVERLAY (rather than the default Large Screen Mode value of OVERLAY_IMAGE).
(I have now corrected my post above to avoid any confusion for other users reading this thread.)

This is also what I see in your gallery (where the caption area sits at the foot of the gallery and spans the entire gallery).

Setting your gallery to use Large Screen Mode will allow you to use captionPosition to position your caption area elsewhere.

Apologies for the incorrect information previously but I hope that this helps to clarify things.

The configuration options available to give a drop-shadow on the main image are as follows:

• imageShadowColor - Color of shadow around main image. ('Customize -> Color')

• imageShadowBlur - The amount of blurring of the main image shadow (pixels). (Customize -> Main Image')

Please note that the drop-shadow on the main image is a subtle shadow which is applied to all sides of the main image rather than an embossed effect.
Here is an extreme example to demonstrate the effect:

That's great! Thank you for letting me know.

You're welcome!

Thanks for the link!

Incidentally, I've moved your query from the Feature Requests thread to its own topic here (just to keep this conversation from obscuring feedback and suggestions over there).
Of course, if you have any feature requests that follow on from this conversation (or any other ideas), please feel free to post them in the Feature Requests thread.
Thank you.

The icons on the Button Bar display the actions that will take place when they are clicked (rather than reflecting the current status).
The Audio icon with the cross signifies that the audio will stop when clicked.
The corresponding rollover tooltip text is in line with this, too.
When you hover over the Audio icon with the cross, the tooltip text reads "Pause Audio".

The AutoPlay icon works the same way (i.e. click to do what the icon signifies).
A traditional triangular 'play' icon is displayed when AutoPlay is off (the user clicks the 'play' icon to start AutoPlay) and a 'pause' icon is displayed when AutoPlay is active (the user clicks on the 'pause' icon to stop AutoPlay).

If you want to reverse the way the Audio icons work, then open the gallery's 'jbcore/classic/theme.css' file in a plain text editor and change lines 855 to 861 (inclusive) from:

.jb-bb-button.jb-bb-btn-audio:before {
    content: "\e00c";
}
.jb-bb-button.jb-bb-btn-audio.jb-status-playing:before
{
    content: "\e00d";
}

... to:

.jb-bb-button.jb-bb-btn-audio:before {
    content: "\e00d";
}
.jb-bb-button.jb-bb-btn-audio.jb-status-playing:before
{
    content: "\e00c";
}

If you want to change the rollover tooltip text in your gallery, then you can do so via the languageList configuration option.
This option is not available in the JuiceboxBuilder-Pro interface and must be added to your gallery's configuration options manually.
Please see the International Gallery Text support section for details. (The languageList configuration option was originally intended to be used for translating rollover tooltip text but can just as easily be used to modify the default text.)
Information on how to manually set configuration options (either in the 'config.xml' file or in the embedding code) can be found here.

I hope this helps.
Please let me know how you get on and if I can be of any further assistance.
Thank you.
