TURN YOUR LAYER COMPS INTO THEIR OWN DOCS

If you're using layer comps to compare different layouts within the same image, you can share these comps with people not on your network (or without access to your computer) by creating a separate document for each layer comp. This makes it easier to email them, and easier for your recipient to view them. Luckily, you don't have to do this all manually; just go under the File menu, under Scripts, and choose Layer Comps To Files.
