That goes a long way to clear up the issue.  Assistance like this
IS detrimental to the cause.

The happy middle ground is to put the text somewhere else.

I'm now very confused.  Then again, maybe I have been all my life.  If the
alt attribute contains the same text as an image, is the image/text
considered accessible?  Can magnifiers enlarge tool tips?  What magnifiers
should I install to test with?  Assuming images are used, where is the happy
middle place that satisfies the needs of as many as possible?

Still trying to understand how to do the right thing when it comes to images
with text...

LOL   I know that feeling about being attacked by both sides.

I mean the image degrades when blown up at about 5x on magnifiers.

I think images are good also though,  For cognitive problems, icons are
much easier to deal with then text.

I just think if you have images with text in them, the text should be
accessible.  One example I can come up with quickly is the copying of text
into a reader such as Readplease
