Oh, so the gallery name isn't just the immediate gallery, but the full 
lineage of the containing gallery.  Was it done that way for a reason?  
I can see that it makes it easier when displaying the lineage on the 
gallery display page, but is it used for anything else?  What would 
break if you just stored the containing gallery of the image and not the 
full lineage?  Because if you did that, it would make it much easier to 
build the gallery move function.  Can't you still get the lineage from 
the gallery information (via getParent() or some similar call)?
