Neither Chrome nor Firefox knows how to display X bitmap format and for Chrome at least, I've been unable to find an extension to do the conversion (didn't hunt for a FF extension). I can clearly download the whole kit-n-kaboodle, use any of a number of different tools to convert the images from xbm to png, then view things locally. I finally figured out that Opera supports xbm and downloaded it. I wonder though, if there is a Python-based web proxy out there which can transparently transform "obsolete" image formats like xbm into png, jpeg, presumably using PIL? Thanks, Skip
