I kenneth....
Sorry for the late reply... I thought I had checked the box to receive an email on reply... but I think I missed it... I just checked out of curiosity and saw your note.
I will see if I can put together a small project to show the issue... but in a nutshell, the gallery does not rebind the images on any post back after the initial load. So if I add a new record to the datagrid, I can't simply rebind the grid, I have to do a redirect back to the same page to get the gallery to bind and load the images.
