Are you unhappy with the thumbnail version of your brand’s logo as it appears next to your Facebook fan page’s status updates? It could be because your logo is circular or because you have taken full advantage of the pixels allowed, and a long, tall rectangle doesn’t fit nicely into a square avatar.
If you need to adjust the view of your fan page’s thumbnail, click Edit Info –> Profile Picture –> Edit Thumbnail.
A box will pop up giving you the option to “drag to adjust” the image or to check the box to “scale to fit”.
Make your selection and then be sure to click “Save” before viewing your changes.
