gallery fixes + spotting where the propagateDataType=POST, etc. 'thumbnail' request should go in case someone is preloading the gallery (which currently fails: the gallery loads the _actual_ images in the preview pane (which is a HUGE load when dragging very large images in there!), plus we want the gallery not only to deliver a list of image paths+captions, but also a set of file objects which contain such info as thumbnail paths, so user code can use those same thumbnails in their gallery (pre)render code, similar to the 'select file/image' mode)
