When sharing an image from Google Drive, you'd be give a link like this.
https://drive.google.com/open?id=0Bx-DkxiKdNS_SnFyVXFLREZpbmc
However, this opens the image within Google Drive's image viewer.
Work around would be to use the following, replacing FileID with the ID above.
http://drive.google.com/uc?export=view&id=<FileID>
Hence, we will have to the following link which will take us directly to the image.
http://drive.google.com/uc?export=view&id=0Bx-DkxiKdNS_SnFyVXFLREZpbmc
This is especially helpful if you're trying to create a Gmail Signature.
