OK. Test 11 checks for that (text within image must be in alt text):

We don't have a test for this yet.

What we're losing here is the description of the image.

Shouldn't we use Alt text as described by success criteria 2 (guideline 1.1,
level 1) "convey the same information" as the image? Why not use the INPUT
element's title attribute to describe the purpose of the INPUT element? This
seems to be more semantically correct. It's a similar to what test 191 is
all about:
http://www.w3.org/WAI/GL/WCAG20/tests/test191.html

The basic idea is to keep Alt text as a description of the image. Use the
title attribute for these other purposes.

Wondering,
Chris
