[aprssig] active station image

[James Jefferson Jarvis]

Hi Martin,

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

http://db.aprsworld.net/datamart/active-image.php?call=kb0thn-12&minutes=20

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:
http://db.aprsworld.net/datamart/active-image.phps

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

<img 
src="http://db.aprsworld.net/datamart/active-image.php?call=kb0thn-12&minutes=20" 
width="50" height="50" alt="KB0THN-12 status" />

Thanks,

-Jim KB0THN
