Transparent GIFs

Look at the source for this page. You will see that the same image is used four times and that the difference between them is the background color of the cell it is displayed in.

HOW TO MAKE A TRANSPARENT GIF:

  1. In the NEW IMAGE dialog box select transparent
  2. Draw your image (make sure the background shows through in a lot of the image area or else there is no point to making a transparent GIF).
  3. Before you save your image select IMAGE->MODE->INDEXED...
  4. When you save your image make sure you select GIF as the extension type.

ASSIGNMENT: You will create your own transparent GIF and display it in a three by three table. Your transparent GIF will contain at least four different colors
