Hi Martin,

It took me a while to get to it, but I've now implemented this feature in 
aprsworld.net for you.


Will return a green single pixel PNG image when KB0THN-12 has been heard in 
the last 20 minutes. Or a red pixel if KB0THN-12 has not been heard in the 
last 20 minutes.

Here is the PHP code to implement this, in case you are curious:

To make this work for your website you can add a HTML <img> tag. For example:

width="50" height="50" alt="KB0THN-12 status" />
