import images from Google Drive
1.) client sends image to be included in mock-up to Gmail address
2.) save the image directly to drive from Gmail
3.) switch tab and import image from Drive into mock-up
no disk, just cloudy blissfulness
Balsamiq has Google Drive support which is quite nice (you can directly store project in it) and have a general Google Account support (don't need to create another account) and Chrome support (appear as an app). It would be nice if moqups had that too.
