Hmmm. Dealing with *ahem* real people *spit* a lot, I've noticed that it's
common for the concept of the first of anything being numbered as zero is
one that many people struggle to grasp, so I wondered if I'd had that in the
back of my mind when implementing that. I guess I either didn't, or I might
perhaps have a higher opinion of RISC OS users.

I should have added that those approaches rest on the assumption that any
alt text is simply the leafname or a set text.
There *is* a way to use the alt text function and end up with meaningful
text, and that's to maintain a script where the first process is the alt
text insertion, and the rest a series of replaces - one for each image,
replacing its leafname (in an alt="*" context) with the appropriate
The drawback is that for an image heavy site is that it can be slow - and
every time you add a new image, you need to add another replace to the
script. It's a bit too easy to forget to do that.
