I was previously unaware of the collection of online images of surviving fragments and manuscripts of the "other gospels" online collected by Andrew Bernhard. He also has available English translations and background material.
His collection contains:
Gospel of Judas (and all of Codex Tchacos)
Gospel of Mary
Gospel of Peter (which is the newest addition)
Egerton Papyrus 2
Infancy Gospel of Thomas
Infancy Gospel of James
Gospel of the Ebionites, Nazareans, Hebrews
Not all of these sources have links to their papyri, but many do--a most useful webpage.
