UBB Code[..img..]http://www.explorerforum.com/data/2/medium/71fenders2.jpg[../img..]
That's straight out of your program... PhotoPost created the code for users to be able to link to photos in the PhotoPost Gallery. The "UBB Code" box is not a hack, it's "out of the box"... Being so you should not have made a change that would alter the links that your "UBB Code" box produced.
If I switched to another "brand" of Photo Gallery software like you did by switching from UBB to
Vb I would expect problems. However, I didn't switch brands, I just "upgraded"...
