Images - Section 4 (of 6)

Poor use of images is the greatest cause of basic accessibility failures on the web. Follow this simple guidance to ensure that your site does not prevent many people accessing the contents of your site.

Some people can't view images, for example:

• people who are blind who use speech browser (screen reader) software;
• Braille output software and hardware.

Some people choose not to display images, for example:

• people on slow connections with 'images off';
• users of phones, PDA's and text only browsers

Some images are often used inappropriately, for example:

• images that should be text:
  • these lose the flexibility that real text has
• images in the wrong format:
  • these can appear blurred and/or increase download time
• images not described properly:
  • these are impossible to interpret for people who cannot download the image
