* in repository, helped with lots of functionality
* Purpose: format HTML tags for the image
* Input: name = name of image (required)
* Input: file = file (and path) of image (required)
* border = border width (optional, default 0)
* height = image height (optional, default actual height)
* image =image width (optional, default actual width)
* basedir = base directory for absolute paths, default
* is environment variable DOCUMENT_ROOT
*
* Examples: {image name="images/masthead.gif"}
* Examples: {image file="images/masthead.gif"}
* Output: <img src="images/masthead.gif" border=0 width=400 height=23>
