Making small gifs Avoid verticle patterns. Try to save files at lowest possible bit depth while monitoring quality. Images with subtle gradations will need to be dithered. Images with solid areas of color will look fine without dithering. Use adaptive palettes for photographs saved as GIFs.
Transparency greatly reduces file size.
Include image size in image tag. Viewers log onto the web using different computers with different color cards, monitor types and sizes. Use Tying Elements. Work with Grids- line things up. Consistency- make a web site not a series of pages.
