Simple Composite

Hi,

I seldom use PS and when I do it is for simple stuff like photo cropping. Once in a while I need something more involved like the ability to line up three separate photos taken in vista sequence and line them up in one image.

How do I do this?

I have tried simply opening a new file and opening the three images in that file so I can can manipulate them into order but I cannot seem to make that happen. Might someone please tell me how to do this?

Thanks!
