An extension to format pictures when printing them via Google Cloud.Made for Jade, this extension serves as a formatting tool when printing out images. Currently you can only drag and drop images onto the tiles, however in time this may change to allow for file uploading and other good stuff.
The settings are fairly simple; set your paper, set your images, drag and drop, click print.
IMPORTANT: I haven't been able to set printer settings, you will have to do this yourself.
