Facebook's app center has opened it's doors to apps but there seems to be quite a few images that need to be created to get it live. To keep them all neatly together and easy to keep in track I thought it would be handy to have a .psd with all the image sized layed out as smart layers so they are all just a click away. As a bonus I have also setup the slices so it's ready to export and upload to Facebook.
It's still rough around the edges, but here it is. Please download, use and modify as you see fit :)
