After selecting multiple images on the 'Images' tab (by using Ctrl+Click or Shift+Click), go to 'Images -> Delete' from the drop-down menu at the top (or press 'Ctrl+D') to delete the selection.

I am glad you have been able to resolve your problem.
Thank you for posting back to let me know.

Try using the embedding code I posted above (in this post), without 'public-html' in the paths.
If this does not work, try the following:

<!--START JUICEBOX EMBED-->
<script type="text/javascript" src="/~davidfreemanphotography.co.uk/Galleries/TestGallery/jbcore/juicebox.js"></script>
<script type="text/javascript">
    new juicebox({
        containerId : "juicebox-container",
        galleryWidth: "700",
        galleryHeight: "750",
        backgroundColor: "rgba(0,0,0,1)",
        baseUrl: '/~davidfreemanphotography.co.uk/Galleries/TestGallery/'
    });
</script>
<div id="juicebox-container"></div>
<!--END JUICEBOX EMBED-->

A possible solution might be to set up a single XML file with the gallery configurations you'd like to use. Let's call it 'preset.xml'. (There would be no need to worry about any image data in this file. It would be used only for the configuration options.)
In your PHP file which generates the XML data for each gallery (pointed towards via the configUrl option), you could read the 'preset.xml' file and copy all the configuration options (the attributes to the opening <juiceboxgallery> tag).
Something along the lines of the following should work although you may need to modify it to suit your own needs.

<?php
$filename = 'preset.xml';

$values = array();

if (file_exists($filename)) {

    $dom_doc = new DOMDocument('1.0', 'UTF-8');
    $dom_doc->load($filename);

    $settings_tags = $dom_doc->getElementsByTagName('juiceboxgallery');
    $settings_tag = $settings_tags->item(0);

    if ($settings_tag->hasAttributes()) {
        foreach ($settings_tag->attributes as $attribute) {
            $name = $attribute->nodeName;
            $value = $attribute->nodeValue;
            $values[$name] = $value;
        }
    }
}

$new_dom_doc = new DOMDocument('1.0', 'UTF-8');
$new_dom_doc->formatOutput = true;

$new_settings_tag = $new_dom_doc->createElement('juiceboxgallery');

foreach ($values as $key=>$value) {
        $new_settings_tag->setAttribute($key, $value);
    }
}

// Create image data here

$new_dom_doc->appendChild($new_settings_tag);

echo $new_dom_doc->saveXML();
?>

Alternatively, if you have only one embedding code block, you could simply set your configurations in your embedding code, rather than in the XML file. Please see here for details.

The size of the navigation buttons can be made larger by increasing the value of the navButtonIconSize configuration option (in JuiceboxBuilder-Pro's 'Customize -> Main Image' section). (There is no need to change the icons.)

With regard to your problem with the 'juicebox.dev.svg.zip' file, I have just downloaded the file myself and it is OK.

If you would like to check the integrity of the file you have downloaded, it should have the following properties:

You can check the file's SHA1 hash with a program such as HashCalc (free).

If the file you have downloaded does not have the properties above, then please try downloading the file using a different browser (Firefox, Chrome, Safari, Internet Explorer, Chrome).

If the file you have downloaded does have the properties above but you are having trouble extracting the file, then please try a different unzipping program such as 7-Zip (free).

When using the WordPress Media Library as a source of images for a gallery created with WP-Juicebox, Juicebox will display all images attached to the post containing the gallery.
However, it looks like you have no Media Library images attached to the post containing your gallery.
Go into your Media Library and check that your images have been attached to the correct post.

If you find that you you have no images attached to the post (which is what your gallery's XML file currently suggests), you can either:
(1) Attach images to the post from within the Media Library itself. (Please note that WordPress allows you to attached Media Library images to only one post so if you have images that are already attached to posts and you wish to include them in a WP-Juicebox gallery, you will need to upload them again.)
... or:
(2) Edit the post containing the gallery, click the 'Add Media' button (above the editor's toolbar) and add images to the post in the pop-up window.

There is no need to change your browser's homepage.
Just go to that web address (copy and paste it into your browser's address bar when you need to) to go to the Java download page.

Certain browsers (IE11, Chrome and Opera) have security restrictions which prevent the loading of XML files (like the one used by Juicebox to store the configuration options and image data) locally. There is nothing that can be done to circumvent this behavior.
Please see these FAQs:
When I view my gallery locally in Google Chrome, I see the message "Juicebox does not display locally in Google Chrome". Why?
When I view my gallery locally in Opera, I see the message "Juicebox does not display locally in Opera". Why?

If you want to view your gallery on your own computer before uploading it to your website, please preview it in either Firefox or Safari.

If you are referring to the way that the caption area fades out with the image and then snaps back into place, then this is unavoidable with the configuration options your gallery uses.

The way that the caption area appears and disappear is dependent on two configuration options: captionPosition and imageTransitionType.

If you want your caption area to fade in and out, then set captionPosition to BELOW_IMAGE or BELOW_THUMBS or BOTTOM or OVERLAY and imageTransitionType to FADE.

Otherwise, to make the caption area transitions less noticeable, try setting your captionBackColor="rgba(0,0,0,0)" (transparent) and set the caption text to a contrasting color (such as black).

As iWeb creates both your main page and the page containing the iframe, it should be possible for both these pages to use the same Doctype Declaration. Unfortunately, I am not familiar with iWeb but their own support pages should be able to help you with this.

You can correct the validation error in your iframe code by changing:

<iframe src= 
http://www.scatturando.it/Gallerie/panorami/index.html
style="width:1200px; height:900px; 
border-color:#990033; 
border-style:solid; 
border-width:0px" 
scrolling="yes" > 
</iframe>

... to:

<iframe src="http://www.scatturando.it/Gallerie/panorami/index.html" width="1200" height="900" frameborder="0" scrolling="no"></iframe>

(Use double-quotes around the 'src' attribute.)

I have viewed your gallery in IE11 and it displays (though with problems which may be due to the use of the iframe, the widget code and the differing Doctypes used).

Do you see the flashing problem when viewing the gallery on its own web page? http://www.scatturando.it/Gallerie/panorami/index.html
If so, what browser(s) so you see this flashing problem in?

I do not know where your ASK Toolbar came from but it did not come from the Juicebox-Lite download zip package from the link on our own download page.

If you would like to check the integrity of the file you downloaded, the Juicebox-Lite v1.3.3 file should have the following properies:

Filename: juicebox_lite_1.3.3.zip
Filesize: 1,721,498 bytes
SHA1: 4cfdd4d1d525f6982f5c20b1e40210788eda17ff

You can check the SHA1 hash of your file using a program such as HashCalc.

If your file does not match the information above, try downloading it using a different browser (Firefox, Internet Explorer, Chrome, Safari, Opera). Perhaps your browser has been hijacked and your web browsing has been compromised. Please see this web page for further details.

Please note that uninstalling and then reinstalling JuicboxBuilder-Lite will not remove the ASK Toolbar as JuicboxBuilder-Lite has nothing to do with the ASK Toolbar.
Try a web search with terms such as 'remove ask toolbar' or 'uninstall ask toolbar'. There are many web sites with instructions on how to do this.

What browser(s) and/or device(s) do you see this flash in?

Try viewing your gallery on its own web page to see if the problem still occurs: http://www.scatturando.it/Gallerie/panorami/index.html

The problem may be related to the code on your main page and the method by which your gallery is embedded.
Your gallery is loaded into an iframe on this web page which contains HTML errors: http://www.scatturando.it/Scatturando/G … arkup.html
The entire iframe page is then used as a widget in your main page .

All three pages use different Doctype Declarations (the gallery page uses HTML 5, the iframe page uses HTML 4.01 Transitional and your main page uses XHTML 1.0 Transitional).
Try using the same Doctype Declaration on all pages (I would recommend using HTML 5) and fix the HTML errors on your iframe page. (You can check the code on the web page with the W3C Markup Validaion Service.)

Here are a few other things you could try:

• Try reducing the filesize of your images to speed up the loading process. Your images are currently approximately 400KB each. For web gallery use, you could perhaps reduce the quality a little and have the filesize reduced to approximately 150KB each.

• Try changing the imagePreloading configuration option from the default value of PAGE to NEXT (to preload only the next image in the gallery). Currently your gallery can have as many as 20 thumbnails displayed (depending on the width of the user's browser window) and the gallery can be preloading as much as 8MB of data when the gallery is initially displayed.

• Alternatively, try reducing the value of maxThumbColumns (which will reduce the amount of data initially being preloaded if you choose to use imagePreloading="PAGE").

• Try using a different imageTransitionType (SLIDE, FADE, CROSS_FADE, NONE).

For reference, descriptions of the imagePreloading and imageTransitionType configuration options can be found in the Main Image Options section of the Config Options page.

Juicebox-Lite should be downloaded from our own web site using the download link on this web page: http://www.juicebox.net/download/
This will ensure that your copy of Juicebox-Lite is up-to-date and clean.

We do not bundle (and have never bundled) the ASK Toolbar or any other third-party software with Juicebox-Lite.

The ASK toolbar may have come from a different program (did you install any other software on the day that you installed JuiceboxBuilder-Lite?) or you may have downloaded Juicebox-Lite from a different source.
Where did you download Juicebox-Lite from?

(Incidentally, the ASK Toolbar should have an uninstall entry in the 'Control Panel -> Uninstall a program' section.)
