[Plugin: WP Photo Album Plus] Adding HTML markup into the photo Description

Greetings,
I’ve fully installed the WPPA+ plugin into my site, and it functions great as is.
I’m interested in making a tiny adjustment to it for some extended functionality.

What I’m having difficulties with is adding HTML support into the photo ‘description’ area. I think I have narrowed in on the function where the changes should be made, but I don’t know how to implement them:

function wppa_slide_description($opt = ”) {
global $wppa;
global $wppa_opt;

if (($opt == ‘optional’) && !$wppa_opt[‘wppa_show_full_desc’]) return;
if ($wppa[‘is_slideonly’] == ‘1’) return; /* Not when slideonly */
$wppa[‘out’] .= ‘<p id=”imagedesc-‘.$wppa[‘master_occur’].'” class=”wppa-fulldesc imagedesc” style=”‘.__wcs(‘wppa-fulldesc’).'”></p>’;

}

When I attempt to add HTML markups such as Header tags or Divs into the description area (via Admin panel), on the front-end the code does not display (just shows as <h1>Title</h1>, etc). If it could be adjusted so wppa_slide_description interprets exactly what is in the area as code, that would be wonderful!

I do not have much PHP experience, so my trials and errors have not gotten me far.
Any assistance would be appreciated.

Thanks!
