Thanks - that did it. I knew I was making this a lot more difficult
than it needed to be.
I'd actually tried something syntactically similar to what you
suggested before, but it didn't work:
$(".CustomClass").each(function(i){
$(this).addClass(i);
});
As you pointed out, however, this was trying to assign an int value to
the selector, whereas adding 'index_' to that int gives a string as a
result. I'm really glad you pointed this out - I tried the above
solution first, but the failure there made me go further away from the
solution. Thanks a lot.
And oops about the 'src' vs 'href' - typed 'a' but thought 'img.'
