Does anyone know of a way that i can open a bunch of images in the same document in multiple layers (as oppose to each one in its own document with 1 layer)?

I have a few hundred screengrabs that i need to resize and rather than opening them all 1 at a time and running a batch, id like to be able to have them all open in the same document and just crop it and save them individually after hiding the individual layers.

Regards,

Lee
