I can't get my gallery to work at all. Any hints as to what the permissons are supposed to be?
You would get a better response if you posted in General assistance-How do I forum.
But anyway control panel>gallery settings
Enter all info including what graphics library you have.
Control panel> Forum Settings
Add a forum and set it as a gallery forum. You can't change an existing forum to a gallery forum.
Control panel>forum permissions
Switch to what your gallery forum is.
There are two permission settings for galleries. Set them to what you want file size is entered in bytes not kb
