The title does not show up when I have images off, unless I hover over
the alt text! Which is bloody pointless having to hover all over a page
to see if there's an image there! Simply stating in the alt text that
it's an image, shows up every time, and tells me quickly that there is
an image there, and gives me a brief description of it.
Why do w3c people always insist on making life hard for the surfer?

The obvious alt text would be "company name logo".

The function of alt text is to provide text that replaces an image. The
wording of that text is entirely up to the webmaster.

With images off, IE doesn't treat alt text the same as the "title"
attribute. It displays the alt text, but does not display the title
unless you hover over the alt text. Firefox is just the same. For
surfing without images, the "title" attribute is of no practical use.

Glad you agree.

As you said, one might have one's own reasons for wanting to know if
there's an image there or not. One might also want to know if it's a
meaningless image or not. Personally I would not use any alt text for a
meaningless image, which is why I suggested that user agents should, in
such cases, ignore the image.

Yesh. In which case you might get |image|Welcome to my website|image|.
Whatever floats your boat as you say.

Firefox (haven't checked other browsers) allows the alt text to over-
ride the "title" attribute. If alt="", the title is not shown, and does
not show when hovering over the place where the image would be. (with
images off)
I don't think it's right that one attribute should over-ride another.
For me it would make sense (with images off) to ignore any image that
does not have alt text or a title. If the webmaster wants people to
know there is an image there, he should provide alt text stating what
the image is, and give a brief description of it. The "title" attribute
being next to useless in this case.
