I have designed an extensive site [www.chepstow-walkabout.co.uk] and have just found out to my horror that in Firefox, image text does not appear.
In IE when the mouse pointer hovers over the images on my tourpages, a small white box of text appears giving street directions. I believe in the coding it appears as
<img src="greenarrow.gif" alt="Walk ahead along the High Street">
Why does this not happen in Firefox?
