This is what I found, not sure if it would be consider a bug but if a picture is defined on a display field with a call to a NetWebSource, the generated page will not include the call to the NetWebSource.
Re:GPF. After I changed the display field type from text to SessionValue, it no longer GPF'ed. and when I put it back to Text type, it was fine too. The app the GPF'ed was after a conversion from C9/NT7 to C10/NT10.
Thanks,
