Testing a Facebook Cover Image in JPG
Facebook cover images help to make your profile unique, allowing you to put a large graphic at the top of your page. However, not all images are suitable for use in this way, as Facebook imposes strict size constraints on cover images. Images larger than 851 by 315 pixels are cropped to meet these restrictions, while images smaller than that size are expanded. As such, Facebook's “Change Cover” function allows you to upload a file -- either in .JPG or another image format -- and then test how that image looks as your profile's cover. You can then either use the file as your cover image or revert to your previous cover.
Sign in to the Facebook website and then click on the link to your profile in the toolbar. Your profile page will display.
Hover your mouse cursor over your existing profile image and click “Change Cover.”
Select “Upload Photos” and then select the .JPG file you wish to upload. The image will appear as your cover photo.
Click-and-drag the image to reposition it. If you are happy with the image, click “Save Changes” to make the image your cover image. If you don't want to use the picture as a cover image, click “Cancel.”
- You can also choose cover images from your existing Facebook photos. To do so, select “Choose From Photos” from the “Upload Photos” menu and then click on the image you wish to use.
