Customising Popups

I believe that as of the 1.1 upgrade, you can adjust the position of all the popups on your map in a setting available in the Maps Manager page. Use negative values to move the popup left and up.

I have the same issue as you in wanting a thumbnail image in the popup (similar the Ready! Google maps), but just getting a link arrow instead. I guess that’s not ‘out-of-the-box’ functionality. We need to donate to encourage development!
