I have a Zenphoto install I've used for many years. It's currently at version 126.96.36.199 I just tried to add an image to one of the Albums, using the built-in Upload. It appeared to work fine, but when I click on the image Thumbnail, instead of getting the full size image, I see a LINK made up of the image's title. When I click on that link, the full size image appears.
Is this a configuraiton thing that I have long since forgotten about?
SOLVED: It was a cache issue, both for the thumbnail display, AND for the large image display. Required two separate browser cache clears, one for the thumbnail page, and one for the image page.
