This site is fully accessible as described below:

Scalable
The means by which the text is specified on this site allows a user to choose how big the text will be displayed so that those who find it hard to read small text.

Images
All images that are non-structural (eg. not tiny corners or lines that are only design-related) have 'alt' text - that is a description of the item will appear when you put a mouse over it and it can be read by a screen-reader.  

Screen-readers
For the visually-impaired or blind this site can be read using a screen-reader. We've take special care to ensure that text is not encapsulated within an image (it's bad design anyway!) and if it is to ensure the 'alt' text reflects what was written.
