Some blog engines (e.g. typepad) do not set an extension for the image. As such, I cannot control the input. For the moment, I am using a workaround: \let\normalexternalfigure\externalfigure \unexpanded\def\externalfigure {\dodoubleargument\rssfeed_externalfigure} \def\rssfeed_externalfigure[#1][#2]% {\normalexternalfigure[#1][\c!scale=2000, \c!method=JPEG, #2]}} Notice the method=JPEG. But, I think that I'll need to wrap a custom wrapper anyways, and some pages contain gif images which cause luatex to crash.
