Thanks Cheryl.
Glad you found our blog. As for the PSD files, nope, you can't open them layered in DIP. If you have PS and only know the basics like myself, you can save each separate layer as PNG and then open them in DIP. Otherwise you're stuck with the method in my tut or as an alternative, you can "insert shape" and match them up with the flattened PSD file. This works fine for standard shapes but not so easy with more complex sketches.
