That looks pretty promising. Tell me - would that use thumbnails then?
I assume it would since there is no preview like in the Ximian one.

So you are saying that for each image in the list it would remember the
style last used for it? If so then that fits in with part of what I was
saying in my blog, and does what I was trying to achieve even better
than the way I tried to do it.

Also - if that was the case does that mean that we could choose
individual defaults for the images we are shipping as gnome-backgrounds
? We really should be able to specify that the tiles we ship be tiled
and not streched or centered.

Only things I can say about it is that maybe it should be "Add
Images(s)" and "Remove Images(s)" and that maybe "Style" should be
indented because it isn't a preferences for that Background tab, but for
the image selected.

Sounds good - if there was a way to check if an image is a tile (ie left
lines up with right and top with botton) that would be useful too ;)

Agreed, otherwise people will think the picture is installed and delete
it.

Dobey: I think we both came off like we weren't listening to each other
b4. I just had some ideas I needed to get out of my head. My
imlementation of those ideas may have been flawed, maybe the ideas
themselves, but we're making progress now and I like your mockup.

I really needed to know how images would be displayed to the user before
setting about putting together this module.
