  • How do I overlay maps in Photoshop?

    I am attempting to create a comprehensive map of various archaeological sites in Peru using at least three different scanned maps (in .gif) and a screenshot of terrain from Google maps. I have a MacBook. How do I overlay the maps so that they all line up and are semi-transparent over the Google map base?

    (And how do I take a screenshot in Gmaps?)

  • irregular periods/PCOS?

    I've had irregular periods, even on the pill, and I recently found out this is because of PCOS. However, I've never been sexually active, so I've been ok with not getting a period in the placebo days. Now that I am, how do I know I'm not pregnant if I don't get a period anyway?
