It's quite a good idea, I like it.
I've used filelistbox's before, one thing I don't know how to do is to specify the specific filename as well, since showing the directory will show lots of images, all but 1 or 2 will be just clutter.
for instance I'll need to specify that i the filename it will be
"Map" & Map.Tile(Xval, Yval).Type & "-"

which I'm sure it's not hard, however something which I don't even know how to do, so I doubt the answer will be that obvious.
I'll look it up now, however if you know the answer, mind just telling me.
thanks
