Apparently not, but facebook may discriminate against you if you’re too skinny. Well, if your photo is too skinny, that is.
I recently encountered an issue with posting a photo from an app on my iPhone called IncrediBooth. When I sent the message to facebook’s email to posting system, the images simply disappeared. When I tried a manual upload I got the message as pictured above: “The photo was either too tall or too skinny.”
IncrediBooth’s own internal facebook posting tool actually adds white padding to an image to make the image a square as a workaround but if you want to have a tall, rectangular image, for now you’re out of luck.
Facebook recently implemented this change after users started hacking their profiles to include banners and other assorted stylistic changes as seen on Alexandre Oudin‘s profile. Find out more about the hack to see what I’m talking about, HERE.
