I'd think that this would be easier if Ansel were using the true 
parent->child relationship, right?  If so, it's another incentive for 
working on the datatree driver to futher optimize it.

I would think so.  Gallery works solely on seialized PHP objects... 
which isn't very extensible or pretty.  But it is fast.

I do like the interface, it's just nasty code (all nested tables).  I'd 
like it to be XHTML/CSS with W3C conformance.  But maybe that's asking 
too much.

You can dynamically rebuild a thumbnail for a single image or for all 
images in the gallery.  What use is this?  I'm not 100% sure, but 
thought I'd mention it.

If we are tracking the uploaded date for an image, this should be really 
easy to pull off.  A simple query like SELECT FROM <> WHERE 
Attriubute="Date Uploaded" AND Value>=<Date - 7days>.  If we aren't 
tracking that, we should add it as it is a piece of information that 
does seem to be relevant and would be useful down the road (say I wanted 
to do a search of my images and display all images uploaded between 
certain dates).  The random image should be possible now.

I'm not knocking IM, just stating the fact that there is no alternative 
(unless you count GD1, which I don't).  Actually, most online gallery 
packages that use PHP use IM for the image manipulation functions.  It's 
fast and very good at what it does.  It's just not always going to be 
possible for someone to install it if it isn't already there.

One other thing that I'd like to see is the ability to export the 
caption data for images to a CSV file or something.  Then we could 
import it just as easily.  I know that I can just do direct SQL queries 
to get the data, but it would be nice to be able to create the caption 
file offline and then import it into a gallery.  And if you had an 
export feature, then it's a great way to create the initial template for 
upload (export the empty file and fill in the necessary blanks then upload).

One other question that you might know the answer to.  What are the 
reasons that uploaded images are stored with random filenames and not 
the uploaded image name?  I can guess that it was due to: 1) desire to 
avoid possible collisions, 2) get around naming convention issues 
between windows and unix.  Was there any other reason?
