There has been a lot of talk about people of nefarious nature hiding information in otherwise normal looking images. After hearing about this prospect, I wondered if it was possible to make an image containing runnable perl code. For several days I had trouble getting around the image headers, as they all cause syntax errors. Eventually, Joost showed me the light of the -x switch.
As of now, my user image ktross's user image is a JAPH script, and a picture of a camel.Steps to run:
- Download ktross's user image, also availible at my home node ktross
- Run perl with the -x switch : perl -x perlmonks.gif
- Enjoy :)
The code contained in the image is a re-run of System Independant Rand-JAPH, but I thought the concept was interesting.
