Encode a pic(1) picture into a shareable URL. Returned as png.
A group of examples.

To send a file, try curl pic.mesacsclub.com/url --data-urlencode file@a.pic > url.
On 9front, like so: pic = `{urlencode a.pic}; hget -p 'in='$"pic http://pic.mesacsclub.com/url.
If you've got a program to encode data as a URL, do it yourself.
curl pic.mesacsclub.com/pic?`{jq -s -R -r @uri < pic} > pic.png.
Have a look at the interesting part of the program.
