For some reason, Picasa Desktop software doesn’t allow you to drag photos from Picasa and drop them to other applications or folders. A pretty big nuisance really. iPhoto has allowed this kind of functionality for over a year now. Get your act together Google! In any case, here’s some workarounds for this problem. Use whichever works best for you while we wait for an official fix from Google.
–option #1. select one or multiple files in Picasa > right click > select “open file” > this will open the pictures in Preview and you can drag them from Preview to wherever you want (into your emails, a folder, powerpoint presentation, etc).
–option #2. select one or multiple files in Picasa > click on “File” in the upper left > “Export Picture to Folder” > specify what folder you want > click Export
Neither of these options are great, but I think it’s the best we’ve got for now.
*note: I’m not sure if this problem is Mac only. Any of you able to drag & drop directly on a Windows PC?
