I think the 3rd party apps need to do something to support this. The
JustPictures app didn't work, and then something changed and it works
now - I can share pictures in Glassboard using JP. I'm not totally
clear on if it was a change in Glassboard or JustPictures, but I
choose to give Bradbury the credit. :)
Just curious, are you going into Picasa and choose Share With ->
Glassboard, or going into Glassboard, hitting the camera icon, and
choosing Picassa from that list?
