Frames and Frame Region
The template Creator allows you to place a photo within four corners. The area where user photos are placed is called Frame Region.
The Frame Region is necessary to position a user photo and is a basic and mandatory element for every type of template. The "Frame" type allows you to insert a user photo to the coordinates of the four corners. The frame may not be strictly rectangular. Shifts, turns, perspective positioning, etc. are allowed.
Also, when inserting a photo, you can use standard Adobe Photoshop blendings, layer opacity, masks.
