Soon after the five picture photo stream appeared as part of the new Facebook profile, people noticed you could customize it to give it a predefined appearance. It’s not very difficult to do and takes just a little bit of patience.
The trick is to create five (approximately) 3×2 images (a minimum of 97×68 pixels), upload them to your photos, and tag yourself in them in reverse order. The five images can also be made from a single image of 485×68 pixels split width-wise into five equal images of 97×68 pixels. To get them to appear, conveniently remove the photos in the stream by hovering over each (unwanted) one and clicking on the [x] button in the top right of the picture until the five you have chosen appear. Be careful not to delete all of them or make a mistake as it may delay the ability to upload and retag the photos to get into the stream. I had deleted all of the photos in the stream and then uploaded photos and could tag myself in them (but only once). When I realized I had tagged me in the photos in the wrong order and removed the tags again, I had to wait about two days before I could restart the process.
Send a message, or be creative. Create a mural or a five-pane image set from a panorama. Just remember it is quite easy to have it disrupted when someone tags you in a photo, shifting the others to the right. Ensure you have your email notifications set when you are tagged in a photo to keep the stream in tact.
