Via AWOL, I learn that a Photographic Archive of Papyri in the Cairo Museum is now online. It is mainly documentary material, but one literary codex seems to be involved:
Gospel of Peter: Photos of all the pages of the Gospel of Peter ms. from Akhmim (P.Cair. 10759)
1 Enoch, chapters 1-27 (same)
A list of contents of all the papyri would be a useful addition to the site.
