can u do this ?
if u select in cp "save by membername or no." the script save the "image.gif" as "member.gif" - and at the next time the user overwrite the image.
can u insert radiobuttons in the upload form, so user can select "save ths image as no 1 or 2 or ... 10." so the scrpit save the image.gif as "member_02.gif" or "mebmer_10.gif" ...
hope u understand
and if u do this - do in cp a function there u can select the max. upload images ...
