sorry just to clarify, the problem CAN still emerge even if you view a
prettyPhoto image first, before entering a caption. if you do this,
then enter several captions and try to view photos again, it still
breaks (sometimes it gets into a weird loop even whereby the first
click tries to open the prettyPhoto box and fails, so it closes it,
then the second click opens the loading animation and then does
nothing). basically this is the most unpredictable and difficult to
debug problem i've ever encountered with jquery!
