[...] Some time ago I predicted that image matching technology would become both cheaper and more effective, making it possible to search for duplicate or near-duplicate images the same way that writers do with text while keeping the price affordable. Tineye was, and remains, a major step in the right direction on that front but its limited database, about 1.2 billion has hindered its ability to be comprehensive (Facebook, Photobucket and Flickr alone combine for over 18 billion images).

[...] The biggest problem Tineye has at this moment is the size of its database. According to a recent update, they estimated the size at over 1 billion images. Though that seems like a very large volume of images, Photobucket alone has well over 5 billion images and Facebook has an estimated 10 billion. [...]

True, but he also says that the largest one of those sizes is the ~40kb version shown on photo.php. Even doubling the total data per photo to 80kb doesn’t quite get you to one PB.

Of course, Facebook reduces all photos they upload down to 600×450px, roughly 40k each – while Flickr (for example) stores up to six sizes of each photo including the full original, which could easily total 4MB of data for every photo uploaded from a 5MP camera.

Taking these as averages, that would put Flickr at 7.5 petabytes to less then half of 1 petabyte for Facebook (of actual photo data).
