This is an swesome plugin, Ian, great job!
I have a little problem, however. I used my own icons as place markers, and for some reasons, they are getting resized to a size bigger than their original size that makes them look pixelated.
I've read the FAQ and did a search here, but couldn't find a support answer that fixed my problem. Is there a parameter I can pass to the shortcode so that it keeps the original size of the icon I use as Featured Image? Right now, it's loading the 150x150 pixels version of my marker. How do I prevent this from happening?
