I'm seeing a lot of puzzling "messing about" going on in there, so it's difficult to determine where, exactly, this problem is originating. But as a quick sanity check, open the album project, and navigate to the
Oldest Bars > PA folder. Switch to the
File name view (upper right). Are you seeing a thumbnail for
shareimage.jpg? If so, delete it. It would not have put itself there, so it's difficult to imagine how it got there.
But beyond that, I'm also seeing some signs of problems. You seem to be trying to get the project to ignore JPG images, and use only HEIC's. This is misguided. HEIC is a patent-encumbered beast, and processing of HEIC images in jAlbum is very slow. In short, they should just be avoided. Switch your phone to giving you only JPG's. The small reduction in storage space offered by HEIC just isn't worth the resulting headaches, not to mention the utter lack of support for them in most browsers.
You should never have a JPG and an HEIC with the same base name in a project. This is just begging for trouble. So, when I see this in the control files, alarm bells go off:
20240803_143730.heic 1722978929
20240803_143730.jpeg 1722999557
jAlbum will try to produce a JPG slide image and thumbnail for each of those, but those will, of course, just be duplicates of each other. Lots of opportunities for fatal collisions.
Stick to JPG's.
Then do some cleaning up of your settings. Go back to the default
Ignore pattern, and join the rest of the 21st Century and use
UTF-8 for everything. See screenshot.
