I like your screen name. Share that Sage!
I can't find this display_image thing anywhere in the Sage source, and
perhaps this is a Sage cell specific thing so that Tachyon things work in
that context (it's neither the command line nor the notebook server, so
some custom code may be necessary). I'm not sure where you found the
display_image, though; even in the Sage cell patches to Sage [1] ... but
presumably this is a Sage cell specific thing, given their custom code, and
I encourage you to report it there [2]. Thanks for the report!
