[nottaprob]

Sorry if this is the wrong area or its been discussed before (I didnt find it in a search).
I've got a couple animated pics I want to use for my wallpaper, but when I place them there, the pic is off center & too low. I dont think the size is wrong, not really sure of size to use, but there's also nothing around the pic (like a border) when I check it.
Has anyone else had this problem? Is there something I'm missing or should do to make this right?
Again, sorry if wrong spot or repeat, but looking for some help.
Thanks
Allen
