I have to do a banner for one of my client's Facebook banners with Amoyshare Photo collage maker software. She wants something sitting on top of the little picture that's to the bottom left corner of the banner(that person's profile picture). See, I'm having a little dilemma, being that I have no idea what the coordinates I'd have to put the item/image at on the banner in order to make it look like it was sitting atop the profile picture.

The banner size is 851x315.

Thanks for any help in advance

Dear Eden,
