One other thing to keep in mind is that if you do implement the image 
bucket concept, that you'll have to track the gallery position of the 
image as an attribute because the datatree_order field will potentially 
be meaningless (depends on if you are going to allow a single image to 
be in multiple galleries or not).  I'd suggest storing it as a paired 
value with the gallery (gid:pos) thereby allowing a user to position an 
image anywhere within a given gallery.  I'll have to rewrite the 
reording page, but that should be simple enough.  I'd just replace the 
setOrder() call with a new function in lib/Gallery.php that would have 
the same effect.

Do you intend to allow a user to have the same image in multiple 
galleries?  If so, it might be useful to have a new page for viewing all 
images in a users image-bucket.  That would be where the user could 
actually delete the actual image.  Any deletion from a gallery would 
just remove the link and not the actual image (thereby avoiding the 
reference count issue).  This way you could upload a bunch of images and 
then later arrange them into galleries without having to first assign 
them to a gallery.  The image-bucket page could use micro-size 
thumbnails (1/2 size of normal thumbs?) to allow for lots on the screen 
at one time.  And deleting an image from the bucket would automatically 
remove all of it's attributes, so there would be no gallery orphans 
left, right?

Again, these are just my thoughts... mostly rambles.
