I'm glad that you have been able to resolve your problem but, just to clarify, the problem is with your web server rather than with Juicebox itself.

Essentially, you uploaded an image to your web server with an accented character in its filename and your web server was unable to display it when you went directly to its URL.
(The image happened to be inside a Juicebox gallery folder but this test actually has nothing to do with Juicebox.)
If the browser is unable to display the image directly, then Juicebox will also be unable to display the image in the gallery.

I would always recommend using only web-safe characters for image filenames but, just to let you see that Juicebox can handle accented characters in image filenames, here's a single-image test gallery (created by JuiceboxBuilder-Pro) where the image in the gallery is named "éèâîôñüïç.JPG": [Link deteled.]

As long as the web server is happy with accented characters, then Juicebox will be, too.

Try contacting your web host to see if they have made any changes recently which might be affecting your results.

Unfortunately, enableDirectLinks does not support multiple galleries embedded on a single web page and there is no way to distinguish between galleries with regard to direct linking.

However, this sounds like a prime candidate for the Feature Requests thread.
Please post any ideas you have for future versions over there where they will be seen by the developers.
I do not know what suggestions will be implemented but this is certainly the best place for all ideas.
Thank you.

Thank you for sharing your experiences.

A quick test of my own certainly supports your theory: Flickr-added autotags do not seem to be taken into consideration in API searches.

Here's a Flickr API forum discussion regarding autotags and the API (it's a little old but the information still seems to hold true today): https://www.flickr.com/groups/510356128 … 985879334/

... and here's a Stack Overflow forum thread (same topic; same conclusion): https://stackoverflow.com/questions/312 … h/32556404

Summary:
If you want to use the flickrTags configuration option in your Juicebox gallery, then make sure that you have added the tags yourself (and that you are not using autotags added by Flickr).

Set enableDirectLinks="TRUE" (in JuiceboxBuilder-Pro's 'Customize -> General' section) and each image will have its own unique URL (the gallery page URL with a # followed by the image index number).

For example, to go directly to the 7th image in our Juicebox-Pro Full Browser Demo, use this URL:
https://juicebox.net/demos/pro/full/index.html#7

You'll notice that the # identifier changes in the browser's URL as you select different images within the gallery.

You're welcome!

Yes, your caption size certainly looks good on my laptop screen (the only PC I have access to today).

Incidentally, as you are using image captions and not image titles, an alternative solution might have been to enter your caption text for the image titles (instead of the image captions) as Juicebox assigns a larger font-size for the image titles than it does for the image captions.

There's absolutely nothing wrong with the solution you have implemented (your gallery looks good) but I thought I should mention this as a potential alternative solution which does not require any custom coding.
(Of course, using custom CSS, as you currently do, gives you much greater control over the actual font-sizes being used.)

Unfortunately, JuiceboxBuilder-Pro does not allow for a certain caption to be applied to a selected group of images.

As far as I am aware, the only application which allows batch captioning is Showkase.
Showkase is a PHP web application (installed on your web server rather than your computer) which allows you to create a complete portfolio web site (integrating multiple galleries) online.
Showkase has full support for Juicebox-Pro and the galleries can be created within the application itself in a web browser interface (or created with JuiceboxBuilder-Pro and imported).

Also, you might like to consider embedding your captions within your images as IPTC metadata.
That way, the caption text will become part of the image file itself and wherever the image goes, the caption goes too.
JuiceboxBuilder has the ability to extract the IPTC Document Title as the image title and the IPTC Description as the image caption (so image titles and captions can quickly be set without any manual entry) via the 'Images -> Titles -> Use IPTC Title' and 'Images -> Captions -> Use IPTC Caption' options from the drop-down menu at the top.
You can add IPTC data to images (multiple images at once) in imaging programs such as Adobe Photoshop and Lightroom.
I realise that this would be an extra step in your workflow (prior to using JuiceboxBuilder-Pro) but if every image has its own caption embedded within it, then all captions can be set quickly and easily in a single action.

Just to clarify, Juicebox-Lite (the free version) has an image limit of 50 images per gallery. Juicebox-Pro has no such image limit.

First of all, it looks like your screenshot is showing a gallery folder (named 'christ2019') rather than the template 'jbcore' folder that the Photoshop plugin uses to create galleries.
After a gallery is created by the plugin, there is no need to modify the gallery folder (no need to rename the Pro 'juicebox.js' file to '~juicebox.js' and place it inside the gallery folder).
As long as the plugin has been updated successfully to Juicebox-Pro, galleries created by the plugin will be Pro without any modification necessary.

Also, in your screenshot, I do not see the 'juicebox.php' and 'pswd.php' files (which are present in the Pro 'jbcore' folder but not in the Lite 'jbcore' folder) so it looks like the gallery folder shown in the screenshot is using Juicebox-Lite.

It looks like you'll need to go through the process of upgrading the plugin from Juicebox-Lite (which the plugin comes bundled with) to Juicebox-Pro.
The procedure is outlined on the plugin's support page here.
Here are detailed instructions.
(1) Unzip the Juicebox-Pro zip file (named 'juicebox_pro_1.5.1.zip').
(2) Navigate inside the extracted 'juicebox_pro_1.5.1/web/' folder.
(3) Copy the entire 'jbcore' folder in this location: 'juicebox_pro_1.5.1/web/jbcore'
(4) Paste the entire 'jbcore' folder inside the 'Presets/Scripts/Juicebox/' folder (in your Photoshop folder).
(5) Navigate inside the 'Presets/Scripts/Juicebox/jbcore/' folder and rename the 'juicebox.js' file to '~juicebox.js'.

Once the plugin has the Pro 'jbcore' folder in place, it can only create Pro galleries.

Please double-check that you are using JuiceboxBuilder-Pro rather than JuiceboxBuilder-Lite.
JuiceboxBuilder-Pro creates only Pro galleries (it cannot create Lite galleries) and JuiceboxBuilder-Lite creates only Lite galleries (it cannot create Pro galleries).
Check your JuiceboxBuilder version (Lite vs Pro) via the 'Help -> About...' option from the drop-down menu at the top.

You can quickly and easily check whether a gallery is Lite or Pro by looking for the Juicebox logo.
All Lite galleries have the Juicebox logo/link in the lower right corner. This branding is not present in any Pro galleries.

I hope my notes above help.
Please let me know how you get on and if I can be of any further assistance.
Thank you.

Edit:
Just in case your browser is caching and using any Lite files, be sure to completely clear your browser's cache before reloading your gallery's web page.

You can set a URL for the Back Button via the backButtonUrl configuration option (in JuiceboxBuilder-Pro's 'Customize -> Back Button' section).
The URL can be a relative path (relative to the web page containing the gallery's embedding code) or an absolute path (such as http://www.example.com/index.html).

Just set backButtonUrl="http://www.fobgfc.org/?page=gallery" and all should be well.

For reference a list of all Back Button configuration options can be found here.

Many thanks for the details.
As I noted previously, the internal browser within Messenger is not a supported browser so if you share any links to Juicebox galleries within Messenger, it might be worth adding a note along with the link saying something like "For best results, please view in Safari or Chrome."

However, I am very grateful for the extra information that you have provided and I have passed it on to the developers.
Thank you for reporting this issue.

(1) Enter your gallery's baseUrl embedding code into a 'Formatting -> Custom HTML' Gutenberg block.

(2) Upload your gallery folder to your root directory and use a leading slash in your embedding code paths to denote your root directory. This should work with any permalink structure. For example:

<!--START JUICEBOX EMBED-->
<script src="/gallery_folder/jbcore/juicebox.js"></script>
<script>
    new juicebox({
        baseUrl: "/gallery_folder/",
        containerId: "juicebox-container",
        galleryWidth: "100%",
        galleryHeight: "600",
        backgroundColor: "#222222"
    });
</script>
<div id="juicebox-container"></div>
<!--END JUICEBOX EMBED-->

I hope this helps.

You're welcome!
I'm glad to hear that you have found the cause of your problem.
Thank you for letting me know.

That's certainly the best way to incorporate videos into a Juicebox gallery (to use a gallery image as a link to a corresponding video).
Thank you for sharing your technique!

For others wishing to try this, the linkURL (the link to the video) will be opened when the 'Open Image' button on the gallery's Button Bar is clicked (when setting showOpenButton="TRUE" in JuiceboxBuilder-Pro's 'Customize -> Lite' section) or when the main image itself is clicked (when setting imageClickMode="OPEN_URL" in JuiceboxBuilder-Pro's 'Customize -> Main Image' section).
