Test case for WCAG 2

Today a client presented me with a query which makes an interesting 
'test case' for WCAG 2.

If he uses a CSS technique to replace a button with a background image, 
is this inaccessible? In practical terms, yes. If I am a sighted user 
with images disabled then I see nothing at all.

But it doesn't technically contravene WCAG1.0. So I looked at WCAG2.0 
expecting to find something along the lines of 'make sure it is usable 
with images turned off' as an item. Nope.

Any thoughts?
