Another approach based on that idea might be something like:

$ImgTagFmt="<img src='\$LinkUrl' alt='\$LinkAlt' title='\$LinkText' />";

However, the caption isn't passed into the image handler function. Which 
is reasonable given it's not part of the image tag.

Thanks, that seems like a workable solution, although I've not yet been 
able to find a selector that can get text after the BR.

Options for a more rigorous solution might be:
1] Since the caption is not currently part of the image it makes sense 
the caption is not passed as a parameter into the image parsing 
function. Is there a possibility to change this?

2] Or, allow for a separate definition of ALT and TITLE within markup. 
Possibly separate the title from alt with another pipe delimiter.

3] Allow for some form of styling to be put around image and table captions.

Option [3] is probably the more generally usable, with the creation of 
some form of $CationFmt variable. If this seems a reasonable approach, 
I'll add a PITS entry.
