using custom "button" instead of standard "submit" form element

I can't figure out how to tell which button was pressed by a user when i'm using a "button" instead of a standard "submit" form element. This works: <input type="submit" name="parent" value="foo"> $parent will equal "foo" This doesn't work: <button type="submit" name="parent" value="foo"><img src="icon.gif"></button> $parent will equal "<img src="icon.gif"> NOT "foo" How do I get the value of "foo" to be returned in $parent and still use a graphical icon instead of a standard submit button? thanks, durwood (durwood@berzerker.net)
