Basically you define this through Usergroup permissions and Category permissions.
If your gallery is integrated with a forum, you first need to set up the usergroups in the forum.
Then go to the PhotoPost admin panel > Edit Usergroups
At the bottom of this page see:
(Refresh usergroups from your forum software?)
After you have done this, the Usergroups created will be displayed.
Then Edit PhotoPost Usergroups and select what each usergroup is entitled to do.
> Save Changes
You will need to move your members at the forum into their respective usergroup.
Next step, when you create Categories in your gallery > Edit Category
You will see various permission as to what each usergroup can do in each category created.
- These checked usergroups can view images in this category.
- These checked usergroups can upload to this category,
unless a usergroup's overall upload access is disabled.
- These checked usergroups can post (comments) to this category,
unless a usergroup's overall posting access is disabled.
Note: If you have categories that have subcategories and you want the permissions to be the same for all of them, you can select (at the bottom of the parent category in Edit Category:
Check box to apply these settings and permissions to all children.
So in a nutshell, first set up you usergroups and determine general permissions for each usergroup.
Then set up your categories and determine category permissions per usergroup:
Hope this helps.
You should be able to accomplish what you want.
