Yes, I tried widths and height greater than 1px.
Could you check and share your findings if you want to. Take the code
sample here:
<td><A onfocus="OnLink(this)" HREF="http://sharepoint.xyz"
onclick="javascript:EnterFolder('xyz');return false;">AnyName<img
src="/_layouts/images/blank.gif" class="ms-hidden" border=0 width=1
height=1 alt="Use SHIFT+ENTER to open the menu (new
window)."></A></td>
Here is the associated css:
.ms-hidden {
  height:1px;
  left:0;
  overflow:hidden;
  position:absolute;
  top:-500px;
  width:1px;
}
And with JAWS running, just tab to the link ‘AnyName’ using the
following settings:
1. text link > set to favor title attribute
2. text link > set to favor screen text
I would like to see how equivalent settings in other screen readers
respond to this change. This is what the JAWS links list utility shows
(based on the example code above):
a) when set to favor the title attribute, it displays ‘AnyName’
b) when set to favor the screen text, it displays ‘AnyName Use
SHIFT+ENTER to open the menu (new window)’
I reiterate, a screen reader’s ability to detect an alt text value on
an image link should be independent of it’s text link verbosity
settings—and that was the understanding when this page was tested.
But in this case (from b) above), as the image is a link, JAWS is
treating it’s alt value attribute as screen text.
Hope that helps.
