Hate the way Facebook seems to arbitrarily crop photos you post on your Timeline to fit the square preview windows On the desktop version, you can change which part of the picture shows in the preview when you’re using Facebook through your Web browser.
To do so, pass the cursor over the image and then click the pencil icon that appears in the top right corner of the post. On the menu that appears, choose Reposition Photo. Click the cursor onto the photo and drag the image until you have the crop you desire for the preview window. Click the Save button. Even though you have now made the photo more appealing for friends browsing your Timeline page, the original image remains uncropped and expands into the full view when someone clicks on the preview window.
