Trinity’s Aunt Emilee designed this great banner image in support of Trinity and Cystic Fibrosis Awareness Month, which is sized to work well as a Cover image for Facebook. To change your cover photo to this image, save the image to your computer, then go to your profile in Facebook. Hover over the cover image banner at the top, and a “Change Cover Photo” button will appear in the bottom-right of the image. Click that to upload the image as a new Cover!
Thanks Auntie Em!
UPDATE: Don’t want to leave Google+ users out of the fun; Google+ members also have a cover image option, though the dimensions for that banner are different than the Facebook cover. Below is a banner sized appropriately for Google+; to use it, visit your Google+ profile page, and click the “Change Cover” button in the lower-right of the banner.
