Loadbit loads Psion .PIC files and displays them on the screen. The Series 3 verion only works with pictures with just a black plane, while the 3a version works with black and grey planes. You can move around the picture if it takes up more space than the screen by pressing the arrow keys, or move it by 10 pixels by pressing an shift with an arrow key.
