Random wallpaper changing since update

[mikedo]

This morning for the second time my Droid Charge had new wallpaper when I took it off the charger. I was using something from my gallery that I've had since getting the phone. A few weeks ago, all of a sudden, I had a sepia colored picture of someones hands ( with cross tattoos on the knuckles). I liked it and kept it but thought it was weird. It's not in my gallery and I couldn't find where it came from (actually I would like to find it again). Today there was a three dimensional grid that was interesting . I use Launcher pro. I am assuming that it is related to the phone often getting unlocked in my pocket and somehow downloading these items. I have not downloaded any wallpaper and now when I try to reload the original picture from my gallery it only takes a portion of the picture and so is blown up to a level that makes it blurry. Any ideas of where these are coming from or how to control the changes would be appreciated.
