Thanks! I ended up finding it on some site called MacGUI. There was two versions I found. One was an extension. Didn't really get that to work. But the second one went with the same name but with "v4.02" specified as it's version. Seems to be a seperate program from the other one I found. This one was a Control Panel (only available as shareware it seems. So I have to put up with a nag dialog box once a month on bootup. I suppose this is more then acceptable. I've seen other shareware have much worse nag screen policies and what not, so I won't complain. 
).
It seems to take up 200k of ram though. But for the moment I still have 2.4MB of free ram so for now not an issue. (It does have an option of loading the image from disk instead of ram, so the picture I set only takes up 1K of additional ram).
I will try and find a more suitable wallpaper for it as I just used my avatar as a test.
Also this did not result in the addition of an arror icon near the Apple Menu, so somethine else is adding that in that photo from the seller. Not really something I'm interested in though just noting that the arrow seems to be something else unrelated to the wallpaper program.
