Shaping Layouts
Shaping layouts is quite simple so there are no images that need to be posted for this tutorial. All you really need to do is the following:

1) Open the image that you want to use.

2) Click on the selection tool (next to what looks like a lasso). For the selection type, choose from the drop down list provided.

3) Select the part of the image that you think looks best. Then hit ctrl c, then right after ctrl v, and viola! you have a shaped image!
