Thank you for providing the link to your gallery.
Here is a link to a gallery that expands successfully:
I think the problem is that your gallery's embedding page does not contain a Doctype Declaration.
It is important that each and every web page includes a Doctype Declaration (at the very top of the HTML document) to inform browsers of the set of standards that the code on the web page should conform to.
Looking at your gallery's web page ('camp3.htm'), it would appear that the most suitable Doctype would be HTML 5 so just add the following line of code at the very top of your 'camp3.htm' web page (and all other web pages within your site if they do not already contain a Doctype Declaration).
Make sure that the Doctype Declaration is the very first thing on the page (without even any whitespace before it), before the opening <html> tag.
More information about Doctype Declarations can be found here.
Also, I'm have a heck of a time finding out why this gallery displays as a blank with a rotating hexagon in center:
According to your gallery's 'config.xml' file, the first image in your gallery should be located here: https://www.jacksonforest.com/Logging_P … cn0122.jpg
However, going directly to that location in a browser (bypassing Juicebox), results in an error 404 (file not found).
Make sure that your images have been uploaded to the correct location on your web server and make sure that their permissions are not too restrictive. (Default permissions of 644 for folders and 755 for files should be fine.)
Also, if you have done any manual editing to your gallery's 'config.xml' file, check that the image filenames in the configuration file (the imageURL entries) exactly match the actual image filenames (in the 'images' folder), paying close attention to files extensions (lowercase vs uppercase) as, on a case-sensitive web server, .jpg is not the same as .JPG.
Also, try not to use spaces in your folder names (such as 'Photos_ North'... there's a space after the underscore) as, when in a URL, they need to be escaped (a space will likely show up as '%20' if you copy and paste the URL) and this can cause confusion (and sometimes problems).
Stick with web-safe alpha-numeric characters in the names of any files and folders that you upload to your web server and all should be fine.
Please see section 2.3 of this document for details.
Characters that are allowed in a URI but do not have a reserved purpose are called unreserved. These include uppercase and lowercase letters, decimal digits, hyphen, period, underscore, and tilde.
I hope these notes help you to resolve your problems.
Please let me know how you get on and if I can be of any further assistance.
Thank you.
