Jealous you didn’t think of this first? Facebook’s constant profile changes tend to get annoying, but this one could get a little fun. Until it’s overdone and gets annoying as well, but probably by then Zuckerberg and friends will get bored, yawn, and change the layout again.
If you want to make your own, I’ve gone through several comments to put together a little How-To. Get creative - and send me what you came up with as a photo reply.
Large photo: 180 x 532 pixels
Small photos: 97 x 68 pixels
Top of the large photo should be around 80 pixels above top of small photos.
The difference in terms of breadth between the tall photo and the 1st small photo (the white area) = around 22 pixels.
The white area between small photos = 2 pixels. OR, just make sure the photos overlap a bit, as Facebook will crop them in the thumbnails. Cutting up one large photos into five pieces won’t work.
If you have your birthday, hometown, (etc) info up, you’ll have to adjust these sizes. And don’t forget to tag yourself in all the small photos so they show up in that row!
