ADDING AN AVATAR AND HEADER TO YOUR FACEBOOK PAGE
The profile picture is the image that appears next to every post that goes into the news feed from your Page. The ideal size for a profile photo is 180 pixels by 180 pixels, but it can be larger with different dimensions. You will be able to adjust the viewable portion of the profile picture by mousing over the photo and clicking Edit Profile Picture and then Edit Thumbnail.
To add or change a profile picture:
Step 1: Go to your page by selecting in from the drop down arrow in the top right corner for your personal profile on Facebook.
Step 2: Hover over your profile picture and click on the camera image.
Step 3: Select an option and follow the on-screen instructions.
To add or change a cover image:
No page is complete without a good cover photo. Your cover photo has to be a minimum of 399 pixels wide (most standard photos are fine) and works best if it is sized to 851 pixels wide by 315 pixels high.
If you do use a standard photo, you will be able to position it to fit in the space, but some area of the photo at the top or bottom will be hidden.
Once you have a cover photo that meets these guidelines, click the Add a Cover button and then select Upload Photo.
Choose the photo from your computer, position it on your Page the way you want it to show and click Save Changes.
