Is it possible to use HTML content or iframes instead of images in lightbox html code?

Q: I checked VisualLightBox app. We need consistent look of images in lightbox and open iframed htm pages to show some calculations and details sometimes… So my question is… Is there a way to show html content? Or is there a similar lightbox capable of showing html and which could share the css with visuallightbox? (I don't care about thumbnails, I just need the 'opened window' functionality for both images and html).
Please let me know if there is anything you know about. It doesn't need to be done in app, just send me the modified js file or guide what to do if you know some solution to my question.

A: VisualLightBox app. supports images only.
