Answering some of my own questions... the code above works to set the 
datatree_order value for a given gallery image.  The issue now is that 
the DataTree module isn't datatree_order aware as of yet.  It would seem 
logical and best that the DataTree driver be made to use the 
datatree_order field in addition to the datatree_id field in the ORDER 
BY clauses (let the SQL server do the work, it's better/faster at it 
anyway)...  I'm just very leary of touching the driver as the changes 
aren't trivial (you have to modify all the functions so that they return 
the datatree_order field in the SELECT statement so that it can be used 
in the ORDER BY clause).  Barring that, I can just add some code to do 
it in the PHP pages... but it'll definitely be suboptimal and should be 
replaced at some point.

Anyway, here's a snapshot of what the new reorder functionality looks 
like.  I used a standard Horde::Form for the rendering of the form, 
hence the odd 15%/85% split on the description/order ...  Also, the 
filename is a link to a pop-up with the thumbnail of the image... I 
thought that would be nice so that you could easily see what the image 
was when setting the order.

Note that this does not make use of the _reorder() function... it wasn't 
necessary for this initial version.  I'm not sure what it would be 
useful for in this case anyway.
