OK, the last roll of the dice worked. The key, for them whats care, was when I set the "--alt-maxwidth-400" in the plucker-build options. If I specified nothing, clicking the image would give me a fullscreen version of the thumbnail. If I specified larger than 400, it would tell me "not enough dynamic RAM to display image." Now I just need to figure out why Plucker doesn't actually convert some of the things, like Fucked Company which really is there in the scooped HTML but gives me a blank page via Plucker.
