I love the background images. It really personalizes the profiles, but I do understand why some people would dislike them. I have put a couple on some of my ancestors that are very loud, and the information on the page disappeared.
It really is a matter of personal preference, but I think also the pattern you pick.
I have been looking for a long time for something for my background because Susan Laursens looked so great.
Thank you for all of this information.
