I see one more feature in which the tool could help, related to <a href="http://www.summitpost.org/phpBB2/viewtopic.php?t=54700&highlight=">this topic</a>.
In parallel to the Bulk detacher, we could add (or improve the existing feature ?) to add such possibility:
Attach all pics from an object to another object, of course if both source and destination belong to the same owner. Perhaps with a tickbox "detach from source" in the same time.
Perhaps the Bulk detacher could be a part of it: there would be a source object, mandatory, and a destination object, not mandatory. When the destination object is not filled, it would work as a detacher only.
As for the picture uploader, I still strongly encourage the listbox with all picture tags: hiking, climbing, humour, fauna, etc.
Since SP is not much improved lately with new features, there are many things your tool could do to ease the job of contributors, I'll add them here as they come into my mind
Thanks,
Eric
