Ciao Ian, and thanks for the useful plugin. I recently updated to v1.10.1 and something messed with the marker icons: they are displayed large and pixelized.

Maybe I need to update WordPress?
The ?resize=150%2C150 parameter is requesting a 150×150 px size, which is what it’s getting.
Are you using Jetpack/Photon to host your images? That may be related. When you set the featured image for a marker, make sure you have it set to use the correct size of the original image, and not a resized thumbnail or something.
Yep, I’m using Photon, and I started it the same day I updated BGMP…
Problem is, in WP 3.5 there is no options when I set the featured image… It’s something Photon did on its own. I’ll try to work it out from that side…
