I looked into it a couple of years ago. Not much seems to have changed:
AFAIK the state of play is still that MathML would be best in an ideal
world, but because many browsers still don't know what to do with MathML,
an image with appropriate ALT text is probably safest.

The WebCT one is not very accessible - the equation is rendered as a Java
applet (!), with no alternative for those who can't use Java. (The MathML
expression is in fact present in the HTML code, but only as a parameter to
the applet, and would normally be ignored by any browser.)
