Thank you lonkero! I had the idea but very raw skills to make it happen.
I'm not sure about the notion of adding servers by IP address, I feel like that's going to confuse people into thinking that whatever server IP they put in there will work, totally not the case. The server has to be tracked on Gametracker.com to get this image banner.
I think it would be easier and more straightforward to add every MWLL server on Gametracker (~25) and have check boxes of which to include.
Custom colors should be easy enough...

These values are hex values for the colors used in the image, in this order:
Top Color
Font Color
Bottom Color
Border Color
It is worth noting that I tweaked the sizes of the image banners to attempt to make them more readable and fit on a desktop better. If there is some way to permanently trim the graph and unnecessary parts of the image off, and have it expand to the left instead of the right, that would be much better also.
Let me know if there's stuff I can help on, you seem to know what you are doing way more than me.
