2 VERY simple questions - Need help fast!

Hello everyone…I was either smart enough, stupid enough or crazy enough (or all 3) to take a job where I need to use zbrush even though I’m still pretty new at it and and my deadline is in 3 days I have questions regarding 2 very simple things that I can’t find anywhere in the documentation. First…Is it possible for me to import JPEG’s to use as reference when I am sculpting a tool. I have been able to import a picture but it takes up the whole canvas. I want to import more than one and have them say…on a different layer from the tool I’m sculpting and be able to resize them and move them around the canvas freely. I’m sculpting a skull and I just need a few reference photos right there in my document to copy details from. Seems simple enough but I can’t figure out how to do it. Also…Is there any way to have non-printing guides on screen?. So I can line things up horizontally and vertically…like the turquoise guides you pull down from the rulers in Photoshop. I would really appreciate it if someone could steer me in the right direction. I’m really under the gun.
Thanks in advance
Rob
