how to overlap two photos using blimp photoshop

1. Overlapping two pictures using Blimp:
When making my photo with blimp I first found two photos that I wanted to overlap and save
them. Once I had them both open in blimp I used the Fuzzy Select tool and the Free Select tool
to outline the objects I wanted to make transparent. I then went to Layer, then transparency and
add alpha layer. Once the entire back ground had been made transparent I just had to copy and
paste the photo onto the other photo I chose. Once both photos were overlapping I used the scale
tool to make the overlapping object smaller and the move tool to move the top layer where I
wanted it.
