It is, in fact, a selfie. Link is in front of the camera in what loos like climbing gear, his hand on his chin in a contemplative pose.

A hand that looks...rather odd, actually. It's like his right arm had been dyed a deep black, and there were odd metal geometric shapes encircling his arm. Link's arm doesn't look like that at all anymore - although if Ilphyl's ever seen Link Fuse something, they'll have seen brief Ethereal echoes of it.

More important, however, is the fact that on the background behind him are several sticky lizards.

Link does not answer Ilphyl's question; it's clear that he considers the picture itself explanation enough.
