Re: alt text & punctuation - best practice?

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
