I have been having an issue with some images not been seen in the Gallery. I tried clearing the database and made sure that the images all jpg have been named correctly. When I look on the server I can see that all the original images have been uploaded correctly into their appropriate albums. But when I look into gallery/cache some image sizes are clearly missing. All thumb nail images appear correctly. Its when you click on the some thumb nail images that the new image appears not to show, but some do display. Also the server is showing several unnamed files, which I am told are sym links.
Zenphoto version 1.4.12 [c1d7e8900b] (Official build)
Can anyone suggest what the issue might be?
