One way is to use either Bridge or Mini-Bridge and Place the first document into
photoshop, then select the other photos and drag them into your open document.
I was hoping for something more automated - like Place-A-Matic.
I typicically want to place 20+ files at a time.
You might ask over on the photoshop scripting forum to see if anyone over there knows how to fix the Place-A-Matic script for photoshop cc.
It seems the version you download from the scripts page doesn't work in photoshop cc, but the Dr Browns Services 2.31 that you can install from the
Adobe Exchange Panel from within photoshop cc does, so you might try installing that version and see if it works.
(it seems to work okay in photoshop cc on windows 7)
