Images need to have their revisions exposed in the UI
There is currently a bug here that caused all of the image revisions to be lost. This is fixed in build 20121123-1253. The cause of the bug was that the columnDefinition wasn't set on the blob getters in the entity class. As such they were automatically mapped to TINYBLOB in MySQL and that can only only store 255 bytes of information. As such all images will now have no revisions expect the current one. As for displaying the revisions that still needs to be done.
