You can work with transparency to achieve irregular shaped outlines on images. It is easy to resize any of the objects and a simple "move" function is provided to aid positioning. Guidelines assist placement and help with alignment of objects individually or collectively, visually or by auto alignment, providing fast accurate positioning in the storyboard. Also provided is an "Auto layout" function for simple non-overlapping images - choose the number of boxes required, the height and width, and the rest is done for you.
