Session and User Settings/edit their own images

[Mec4D]

I have question about the setting for users :

Allow users to edit their own images
Allow users to delete their own images

If allow to edit their image mean upload new in place of the old or?
Some members upoloaded wrong size and don't wish to remove own images cose of the comments posted already by other members so they ask me to do this..

Why the edit image don't allow to upload new version of the image of place to remove everything with? This will help me cose with more that 2600 members and almost 2500 images somethimes I get tired just kidding..

Is here any solution for this.. guys?

thank you for your help,

Cath
