Dynamically passing text and url-based images as an input parameter to cf8 report builder

I'm unsuccessfully trying to dynamically pass text and url-based images to a group footer or the detail section via an input parameter or even hardcoded. The field has the attribute 'XHTML Text Formating' set to True. The following are failed samples of a simplified value:

"<img height=’300’ alt=’Document’ width=’300’ src=’http://www.google.com/intl/en_ALL/images/logo.gif’ />"

or

"<img src=’http://www.google.com/intl/en_ALL/images/logo.gif’ />"

This just results in the above text being output. The end result would have various text and images from a database as input by a user, thus the reason I cannot just use the hyperlink information attribute as I could if it were a single known image. I tried rtf and pdf report types. Ideas?
