Internet Explorer PNG DOM Loaded Images

Question

I have a site setup using transparent PNG images that, of course, don't want in IE without the transparency fix applied. Well, the fix is applied but it still isn't working.

div, img { behavior: url('/path/to/fix/iepngfix.htc'); }

I know it's loading the HTC file correctly as an alert(1) fires upon page load. The images, however, aren't transparent. I assume this is because they're being loaded dynamically into the DOM via jQuery.

What I need now is a way to fix this. How can I get these dynamic images to be transparent? :/
