It's important to keep in mind that translating from GIF to JPEG, or vice versa, doesn't work that well. Unless your images started life in one of those formats, you always should start your translations from the original file format. Another trick to keep impatient Web surfers more inclined to wait is to let them see something happening. You can add the feeling of more speed by saving JPEG files with the progressive attribute or GIF files as interlaced. In most browsers, these attributes will make the images appear all at once, then sharpen gradually.
Nothing gets attention faster than a moving image.
Drag and drop to offset a small frame over a large one, instead of redrawing the entire frame to make a light blink or a UFO appear in the sky. Remove redundant pixels. Use one super palette for all of the individual frames in the animation. You won't know until you test. ZDNet and ZDNet logo are registered trademarks of ZD Inc.
