I thought from memory that most text readers ignored the title
attribute, A research paper by Vision Australia ex staff member last
year.
Why not put the image in the CSS background-image:
url("Pics/Thispic.jpg");
You can add onfocus or hover events to change the pic and the page is
still clean for text readers.

Hello!
Here's an issue that's been bugging me for a while and I'd really love
some clarification.
There's been a bit of discussion at my work about where we use an
image as a link that we must also provide a text link beneath the
image as an alternative. The text alternative is usually mirroring
what is included in the graphically designed element. So for sighted
people it's a bit odd and sometimes confusing reading both. We never
use images for main navigation, but occasionally like to add a
graphically styled element for something we're promoting on our home
page.
I believe the justification is broadly for accessibility reasons,
though specifically in which situation is this helping? My
understanding is that:
• screen readers have no problems reading alt attributes (title
attributes in an <a> are a different story though - I've heard mixed
reviews - if someone could clarify?)
• a text only browser will usually read both title and alt
attributes (please correct me if I'm wrong on this!)
• a screen magnifier will enlarge the image as well as the text
• in the case of a user enlarging the text through their browser
settings, the image won't be enlarged and the text alternative will -
the only real scenario that I can see where this technique may
possibly be of use.
So is this really best practice?
Cheers,
Cara.
