Embedded imgs: asfunction won't work with img button?

Having a heck of a problem - I can easily use ahref tags on text to call flash methods from dynamic text: for example:

<a href=“asfunction:_root.clickHandler,2”>GO TO PAGE 2</a>

but if I use this:

<a href=“asfunction:_root.clickHandler,2”><img src=‘img.jpg’/></a>

I get nothing. The image recognizes that it “should” click to something, but I can’t get the image button to call the function.

Any ideas?
