Sure. For example:
http://videokarma.org/showthread.php?t=187889
The thumbnails are gone. On the first post in the thread, if I go into "edit," then "go advanced" it shows the names and sizes of the five images I uploaded back then on AK.
If I try to upload one of those same images into a Videokarma thread, I get a message stating that I already uploaded that picture to the system.
Should I delete the attachments in the original thread?
