Hoto change bg picture without settings applet??

[mads randstoft tellabs com]

Hi!

I have made a simple script that loads a picture from the net and want to place
it as a background picture for gnome...

Now I want the picture to change, say, every hour but how do i make gnome
update the picture it has as background??

I have now used "background-properties-capplet -b .background/background.jpg"
but then every time it happens, the settings windows apear and I have to shut
it down...

How can I update the background image without that hastle??

And are there any such programs already out there?? (I have looked through
freshmeat for a program to change my background images from the net on regular
intervals, but have found no such thing...)
