ShotSnapp or Shot Snapp (I'm not exactly sure how they prefer to be spelled) makes it super easy to make mock ups for marketing pages, presentations, or to share around.
It's insanely easy to use. Select the type of shell (phone or browser window) and then drop in your image. You're literally done at this point, but you could customize colors, size of image, and centering if you want.
They just launched so they only have two shells for now, but it looks like other options are coming soon.
It's seriously as easy as it can be and it's free.
