[Plugin: Events Manager] Images don't show up

Hello, my site is cyclecommute.org
I’m using events manager to publish local critical mass events. My problem is that I can’t get event images to show up anywhere. My wp-contetn/uploads file permission is set to 755, and I’m able to upload and save images, but they are not showing up in the events list.
any suggestions?
