That image importing feature that was supposed to be coming in the next LittleBigPlanet patch? It's probably not going to happen, after all. The Community Manager has made a comment on the official European PlayStation forums to say that while "image importing is very much technically viable ... there are currently no plans to introduce it for a variety of reasons.
"Announcements of future content releases, whether free, paid for, feature update, costume, sticker or whatever will always come through the official websites for LittleBigPlanet and Media Molecule, if you hear of updates through any other source please take it with a pinch of salt until it has been confirmed or denied." So while it's not ruled out for good, don't expect to see it coming any time soon. Better plug that PlayStation Eye back in -- it's your only method of custom image importing for the foreseeable future.
