Congratulation your Plugin for Flickr, Picasa... is the only one working perfectly with the WP 3.3.1. But unlike the rest Photonic doesn't let you post a certain photo. You only can choose "Photos" and then "How many". I think this is a really relevant option. Maybe I'm missing something. Are you planing to add something like this?
Thanks for you time and the good job for the community!
Have a good day!
