Can't really tell from that macro shot what your problem is. In order to hang the screen door, you need to look at the side from the garage and follow the manufacturer directions for hanging it from that side. There is also info at DIY's own forums, along with Askthisoldhouse.com.
Looking at the pic from your angle, it looks like you do not have any brick molding on the exterior side of the jamb. You will have to add some flat stock to the exterior side to hang the door on or order a custom size to fit on the existing jamb
