The link leads to the archive of "published" yukkuri images over at futaba. I am not sure if this is the source of where some/most of you port images over to OYP, but the threads here look well-organized enough that it may help with identifying certain artists.
For example, Unknown_36 appears to be "Letty-Aki". All the other artist names appear to be correctly represented with their respective works.
And if this has already been known / utilized in the past, I apologize for bumping old info~
