I was interested and fiddled abou it. And this seems to work without any extra podparser.

Download this code to pod_img.pl

for (1.10) {
  print;
}

print "dummycode";
[download]

and call

pod2html pod_img.pl >pod_img.html
[download]

the resulting html-file shows an image in most modern browsers! (Officially also in IE7, but I couldn't test it! So please tell me if ...)

PLEASE NOTE: The image data is in one long line, the linebreaks were inserted by the perlmonks-formatter.
