The Disability Discrimination Act says that websites must be made accessible to disabled people. So how can you check that your website is up to par? There are a number of basic tests you can make to address some of the main issues that provide a good start in increasing accessibility to your site visitors:

1. Check informational images for alternative text

Place the cursor over an informational image, for example, the organisation logo. Does a yellow box appear with a brief, accurate description of the image? For users whose browsers do not support images, this alternative text is what they will see (or hear) in place of the image.

2. Check decorative images for alternative text

Place the cursor over a decorative image that does not have any function other than to look nice. Does a yellow box appear with a description of the image? It should not. There is no reason for users whose browsers do not support images to know that this image is there, as it serves no purpose.

Be careful though as this is not a foolproof test. If a yellow box does not appear, this could mean one of two things:

- The alternative text of the image is assigned a null value, which means that it will be ignored by browsers that do not support images. This is the ideal scenario.

- The alternative text of the image is simply not set at all, which means that users whose browsers do not support images will be alerted to its existence but will be unable to find out what purpose it carries
