That sounds like you know the right answer...but I don't understand it.  
Can you point to any documentation of Tcl/Tk's Img extension?  Google 
produced some links, but they seem to be implying that this won't work 
on a vanilla installation.  (I'm not really certain, as they were really 
talking about something else...but that's what it sounded like.)  If 
this is correct, then I guess I must convert all of my images to gif 
files.  (This isn't horrendous, but I prefer that the images be 
something I can look at with a text editor.)
