This addon is a plugin. You need to extract it to your /plugins folder to install it.
Adds a picture gallery to you website for you to add new pictures to your website with seperate folders for everyone to browse. For some reason in my testing phase I wasn't able to disable this, so if you want to disable this addon, you'll have to edit your config file and take the following line out -- $Configuration['EnabledPlugins']['PictureGallery'] = TRUE;
This will add a simple image gallery that only the admin can edit and add pictures to to your website. A link will appear within your menu bar links, and you'll be able to have separate folders for your pictures.
ImageMagick is required for the thumb creation, you can edit your path to ImageMagick in the views/manager.php look for $PATH2IM = ''; and put within the quotes your path to image image. On liquidweb.com's servers its /usr/local/bin/ other servers may vary. Some don't need a path set which is how it is by default.
You can add captions to the images within the dashboard page. Uses a lightbox version of jQuery I had awhile ago on a previous site to show the full size image.
For some reason I cant disable it from the dashboard/plugins page, so if you want to disable it take $Configuration['EnabledPlugins']['PictureGallery'] = TRUE;', out of your config file.. maybe someone can help me with why I cant disable it..?
I'm not sure it it will work if your forum is installed within a separate directory of your site. I know it will work if your forum is installed in your home directory.
Once again, I did use text files to store some of the data for the images, this is to cut down on the database calls and I havent figured out how exactly to use the database and submitting forms yet within the vanilla core. One day soon I will though ;)
