background issues

Have to smaller pictures in my background can't remove,also when I find new background pictures sometimes are multiple small same pics . thks Jerry

 

Can you do a screenshot of the two "small background" pics you can't remove?

Also, with the multiple pictures you're seeing instead of "one large background pic" could be the fact that you have the image set to display as "tiles"

right click on your dektop > go to Properties > on the display properties go to desktop tab > and where it says "position" change to "stretch" on the drop down box.

Course this might not be your problem, i'm just suggesting this because it sounds like it..
