I found another feature I would really like to see.
Since many of us seem to be using 4images with a forum, it would be great if the member group option included a few more settings although I think it is a pretty major code change.
1. registration will auto create a catagory
2. within the group setting, you can set folder (or catagory) size that was created with registration.
Example, I register with the username "Coastie" a new catagory is created with the name "Coastie" and it has an limited set by the admin at 5MB. I can now start uploading images until I have reached my 5MB limit.
If the registration auto create catagory is not possible, I can set the users up with a folder manually, but I'd still like to see a folder size limit.
*edit: After using it a bit more, it might be easier to set an image number limit rather than a folder size. Example, catagory "Coastie" has reached its limit of 20 pictures.
