I have played with a couple of image galleries and gotten them to work properly. One is Gallery 2 and the other is Coppermine.
They both are fine, but Coppermine offers integration with the forum. In other terms, I can configure it pick up the user database from the forum which means that all forum members would automatically have gallery accounts.
Take a peak at them if you like and give them a try.
Be aware, that all data accounts and pictures will be lost if I integrate the gallery with the forum. Regard anything you put in the galleries as temporary!http://www.itiedye.com/galleryhttp://www.itiedye.com/picturesYou can get the url for the image in either program by right clicking on the image and selecting "copy image address". This makes it easy to post images in the forum.
Please post feedback and preferences here!
