- Try to keep the file size of your graphic less than 30K.
The larger the file size of the graphic, the longer it will
take for a visitor to download your page. If your page cannot
load by 30 seconds, most of your visitors will leave your
site.
- You should include a text alternative with your images.
Most HTML editing programs include an easy way to insert
text alternatives for the graphic description.
- Avoid using too many graphics. The total file size of
a page should be around 30K to 60K. Add up the file sizes
of each graphic you have used on one page to discover how
much information must be downloaded for a visitor to view
your page.
- Try to limit your colors used in gif images to the 216
browser safe colors. This will prevent your images from
having a dithered (grainy, or speckled) look.
- Limit the use of animations on your page. These are large
image files and will slow the download time of your page.
If you use animations, they should only be used for the
reason of enhancing the content on your page.
