As I understand it, this is really a style effect, not achange in content (in most cases). So the better way to do it would be to use the :hover pseudo-element selector in CSS2, but I am not sure how well that is implemented. Alternatively, match the onMouseover/onMouseout pair of triggers with an onfocus/onblur pair and get the script to change the alt attribute of the img element whose src attribute is being changed, but that depends on the DOM/script implementations. This can also be done in SVG, using animation. But the requirements to meet SVG syntax restrictions make it a little odd. An example of how can be seen in section 5.2 of the note Accessibility Features of SVG - http://www.w3.org/TR/SVG-access/#Animations - (Technical jargon and content warning). cheers Charles McCN On Fri, 3 Nov 2000, Jamie Mackay wrote: Hi I'm new to this list so please forgive me if this has come up already. Has anyone come up with a solution for making swap-image javascript functions accessible? I know that ideally these should be avoided, but I am keen to push the boundaries of the guidelines a bit and see what is possible. My solution so far has been to simply create a D tag (and a longdesc attribute for the image tag) for the default image and then describe what each image will look like as the user holds their mouse over a different link (for an example see http://www.nzhistory.net.nz/dnzb_exhibs/index.htm ). Is this an 'acceptable' solution? Are there better ways of doing this?
