I am trying to change the default image for an Item in K2 when published without an image. I am using JA-Orisite 2.5 (my sub just ran out, and cant access the forum), and for the life of me, I cannot find the original image so I can overwrite it. I have looked and looked, and cannot find it.. Ideas?

This is literally one of three things keeping me from launching this website, and I've been working on it for over 2 months.

HELP?!
