I upgraded from 4.1.66 as usual and now none of my images are showing.

here's the code I'm using

thumbnail.php?memid={MEMBER ID}&field=profilepicattach&thumbwidth=750&thumbh eight=750

or

download.php?memid={MEMBER ID}&field=profilepicattach

profilepicattach is still listed in my wsngallery_members table and the images are in the attachment folder, so I'm guessing it might be something wrong with download.php and thumbnail.php

Let me know...
