[Athen] Logo as a background image?

[Dan Comden]

Hello,
Your rule of thumb sounds correct.

Generally I think background images of any kind are going to cause
problems, for the reason you noted (not read by screenreaders) but also
because of almost inevitable contrast problems with the text that's
overlaid. Greg Kraus' cool new contrast checker plugin for Chrome can tell
you if it's a problem but it's easier just to avoid the issue if possible.

See WCAG Failure criteria:

and
http://www.w3.org/TR/WCAG-TECHS/F3.html

Important images shouldn't be in the background.
