setting $caption to accept html format

Hey,

I've installed imagefield_extended module to allow imagefield descriptions to have custom-formatted description text, showing html links, etc. I have hacked the module to show that field instead of the standard imagefield 'description,' limited to plain text only and 120 characters or less. Lame!
However, although its showing the description, it seems to be stripping HTML markup from the theme(), and I need to find a way to have HTML characters show.

Is there any way to have $caption keep HTML markup when passed through the theme function on line 311?

if ($imagecache_exists && $thumb_preset) {
      $thumb = theme('imagecache', $thumb_preset, $filepath, $alt_text, $caption);
    }

NOTE: I'm aware I should put this in my theme instead of hacking the .module. This will be done. I'm just making it work here first.

Please let me know. Thanks!

Here is the hacked function: Line 269-334:
