I used to know of a free php image gallery that did this but i cant find it anywhere, if anyone knows of anything similar please let me know. Dynamic reading of folders so lets say the main folders will be the categories, and the folders inside the main folders will be the sub galleries so and if I add folders, images, the script will automatically detect it, instead of using a database type system. Only other feature I would possibly need is to have a description of each main category. If someone is willing to code something like this I would be willing to pay up to $25, or if you have something readily available.
try this and whats good about them ? its free http://minishowcase.frwrd.net/ or http://smoothgallery.jondesign.net/showcase/gallery/ or http://www.notedown.com/?p=12
thanks asterix...that minishowcase one is nice, im not feeling the way the are making use of ajax but it seems to have everything else I need, hopefully it supports sub-categories.
