So, it the header makes it look like a PNG: magister.html: PNG image data, 1242 x 1, 8-bit grayscale, non-interlaced If you look at this in an image viewer, it's as advertised: a long black bar. So what this is is some garbage data with a PNG header, a token PNG image, and some HTML that bootstraps a javascript program whose main body looks like binary garbage. But it's not a self-extracting PNG, it's a very strange…

I can't get this to work; low end laptop with low end gpu. But is it anything like what Rsnake posted on ha.ckers.org? Link: http://ha.ckers.org/blog/20070623/hiding-js-in-valid-images/ Example: https://github.com/christopherwoodall/ImgJs

(Repeated) kernel panic on Macbook Air/Chrome I'm afraid.

Can you post OS and browser versions along with the hardware revision? That sounds bad.
