The photopaint applet uses a series of photo and blended images as a palette. To paint, select one of the color swatches in the palette. A larger swatch will appear to the right of the canvas. Click in the canvas area to paint by revealing portions of the selected image. Clicking and dragging in the larger swatch specifies a particular area of the image to paint with. Clicking and dragging in the scratch (dark gray) area resizes the reveal-paint brush.
