letting a search engine 'see' image text? Pete 10-10-2007

 There's probably a standard answer for this, but it's never cropped up
for me before.

I have a (png) image that includes some text (a labelled group photo
of a conference), and it'd be useful if a search engine can find those
embedded names too -- without redundantly placing them in visible HTML
text. What's a good way to do this?

Some of the text can go in the 'alt' tag of the image, which I suppose
is checked by a search, but that could be a bit long. Suppose I could
use white-on-white like the spammers do... (:-/) I expect there's a
recognized way, though.

<img
src="group-at-conference.png"
alt="Short text equivalent"
title="Some more information"
longdesc="detailed-description.html"

But I don't know if search engines would actually follow the longdesc-link.

> Some of the text can go in the 'alt' tag of the image

There is no alt tag. There is just an alt *attribute*.

Greetings,
Thomas

This is the problem -- I haven't found a (text or otherwise) browser that
sees longdesc at all, so maybe it's unlikely that a search engine would,
either.

I may eventually just have to see if the alt attribute shows up in a
google...

Sorry -- sloppy language... (:-/)

Why not just style descriptive text display: none?

Beware of using ALT. If I turn images off, then I'll see your "hidden"
text in my browser, where you might have captioned your image "Pete (The
Bastard)" :-)

I'd see it if I viewed the source anyway.
