Solved - i think Just in case somone else has a similar issue here is what i did.
At scrollerBeginDrag i set the filenames of the images to empty but kept text field text. At scrollerEndDrag i reloaded the filenames into the images. These images are all thumbnails so they load very quickly, plus there are not that many. This will be done at a museum with a local server and apple airports things (maybe the only bottleneck) so it should be quick. My test was fast with a server in Texas and me in Venice, Italy...wait...Jeez what am i doing at this desk!! Venice! Going to get gelato at the Rialto Bridge!!!
