Instagram (free) is a lot of fun, although it's often criticized as being the "auto-tune for photography." Google+ is the new social networking flavor of the week, so it's natural that the two services should get together. Wired's Gadget Lab has cooked up a recipe for more Instagram enjoyment by hacking a method of joining the two in unholy matrimony, as well as providing other fun hints.
Before I divulge their other hints, let's get to the meat of the matter for those of you who are among the Google+ cognoscenti: getting your Instagrams to Google's Picasa photo sharing site so they can be shared on Google+. Yeah, hopefully this is added to Instagram in the near future. For the present, this is how you do it, folks.
To have all of your future Instagram photos sent immediately to Google+, blogger Charlie Sorrel has you set up Instadrop, which automagically connects your Instagram and Dropbox accounts. Send a photo out on Instagram, and it shows up in a Dropbox folder named Instagram Photos. Next, pick up a copy of the free Picasa app for Mac. From the File menu, select "Add Folder to Picasa" and point it at your new Instagram Photos folder on Dropbox.
The next step is to have Picasa watch that folder all the time. There's one fly in the ointment here -- this means that if you want true real-time updating of Picasa / Google+, your Mac has to be up and running continuously. Go to Tools > Folder Manager in Picasa, select the Instagram Photos folder, and then tell Picasa to "Scan Always." Finally, find the folder in the sidebar of Picasa, click on it, and then select "Enable Sync" from the Share drop-down in the main menu.
That's it. Send a photo to Instagram, and through this complex chain of events the image eventually makes it to Google+, where it is re-shared and commented on by thousands of your friends and complete strangers.
Sorrel has some other great tips in the post, including using your "real" camera to take photos, transferring them to an iPad using the Apple Camera Connection Kit, and then zapping them to Instagram. He also recommends the $1.99 Instaplus app to have much more control over the camera and filters.
