Images - Page 3

Information presented visually is not accessible for everyone. Provide a text description for everything, always use alt and title attributes, and sometimes add redundant links.

Bear in mind that images of bullets or little stars also convey information. They say, "new point" or "this is important". So always use that alt and title attribute. With an APPLET or object, you can also provide a text description in the content of the element.

The rule of thumb is simple. Visual information and motion can be accessible, but see W3C for how to do it properly.

ASCII art? A picture composed of semicolons and periods may be cute, but it can be confusing if it is read to you. Flickering or flashing screens may cause seizures in users with photosensitive epilepsy. Ensure that pages are usable when scripts, applets, or other programmatic objects are turned off. Avoid automatic refresh.

Your image maps should preferably be defined client side. Use the "alt" parameter on all <area> tags and use redundant links. If you must use a server side image map use the "alt" parameter to warn disabled users, and give them alternative links. For example: alt="Server side site map, but text links will follow".
