Sometimes awkward to convert vischeck URL into PNG file.

[GoogleCodeExporter]

Sometimes the URL that vischeck outputs is to long for an HTTP GET request.  
Especially if there is more than one series to display:

$ tool/vischeck.py --colour '000000,00ff00,0000ff'

Would be nice if there was an option to use a POST request to download the PNG. 
 POST requests can be much larger.
