What's it called

[laserblazer]

When a caption appears if you hover over a web image? I suspect that good practice says they should be there but are school websites supposed to have them?

Alternative text.

Set it for all images.

Yes, the reason they are supposed to be there (and descriptive) is for accessability software like screen readers so that the visually impared can still get the information.

There are even laws about it UK Law for websites

Thanks synack, that's what I wanted. We've just had a new website go online www.witton.worcs.sch.uk
it's a damn sight better than the one I did but I have been asked for my comments.
