Bug Description

The gallery appends Date.now() to the end of the image://thumbnailer URI used to load photo thumbnails in order to avoid showing thumbnails for old versions of a file.

Unfortunately this means we never get any hits from the QML image cache, and the image needs to be reloaded more often than needed. Instead it should use a value for the "at" parameter that only changes when the file content changes.
