photo/video sync app

[mrscientist]

for christmas, i got my dinosaur father an optimus v on the cheap for him to see pics/vids of my kids. he'll be using it with wifi only, no 3g. i'm looking for an app that'll automatically sync pics/vids from somewhere (dropbox/picasa, etc.) TO the phone whenever the phone connects to wifi. it needs to be silent/seamless, since he's technologically ignant. any suggestions? thanks.
