Thank you for your reply. However, the point was that when the index.html file was opened in Firefox, I did get the background color specified in the LR plug-in, but the images did not show up.
I checked the forum post and found that the workaround had already been applied previously, so that was not the issue anyway.
I would like to add some more files to show the details, but I find no way to accomplish that at this point. So, here is a summary:
1. There are 72 images in the LR Library Grid View. But when the Web view is activated, I get an appropriate view of the intended gallery except that there are only 7 image thumbnails shown. Within the context of the 7 thumbs, the gallery works fine, text items and formatting all work as expected.
2. When exported to a folder, that gallery folder contains five files: config.xml, images, index.html, jbcore, and thumbs. The images folder and thumbs folder have all 72 images in them. The jbcore folder contains the folder/files: classic, full.html, juicebox.js, juicebox.php and pswd.php.
3. I did look into the javascript file for errors and the only thing found was an extra semicolon that did not make any difference when it was removed, so I returned it.
I am attaching some of these files (not the images or thumbs) below.
