Unbeliever,
The RAM usage is not an issue as you are thinking!
If you take a look at your Windows' Task Manager after playing around with themes etc. you will probably see that it needs +11MB of RAM. But, in fact, it does not need all that RAM at all.
If another program needs RAM Windows XP will, automatically, free some RAM that DeskPhoto is allocating (as well as RAM from other applications).
On systems with less RAM than yours, Windows XP won't let DeskPhoto takes so much RAM for a long time. I also test DeskPhoto in a 256MB of RAM. Everytime I take a look at Task Manager it shows that DeskPhoto uses less RAM than my 512MB of RAM PC.
