Cancel Button should be Added to Edit Image Mode

There should be a cancel button when in edit mode of an image. Right now the only way to go back to the image page without saving is to click the back button the browser. I confirmed that facebook has a cancel button when on edit mode for images. While I know we don't want EasySocial to be just a copy cat of Facebook, I reference them on simple features because these are things we hope for on a profile.
