This would display the "value" as button text. It works, BUT:
- you cannot divert content from data or functionality
- you have to modify code if you want to modify your page
Something that might not be worthwile, depends on the project size.
However, if you need to act on a button, you _need_ to test for something,
be it the name or the value.

I still don't get it - maybe you could show us your approach to the
solution so we can grasp the problem?

Now that's more easy:
<form name="myform">
<input type="hidden" name="button" value="">
... something here
<input type="image" src="img_1.gif"
onClick="document.forms['myform']['button'].value='button_a'"><br>
<input type="image" src="img_2.gif"
onClick="document.forms['myform']['button'].value='button_b'"><br>
<input type="image" src="img_3.gif"
onClick="document.forms['myform']['button'].value='button_c'">
</form>
This will give you a $_REQUEST['button'] containing the button value. Note
though that this doesn't work if JS has been disabled in the browser, or if
the "browser" doesn't support JS at all.
