Hang-a-Pic greatly simplifies the tedious and sometimes difficult task of hanging multiple, equally aligned pictures, mirrors, decorative plates, candles or any other wall mounted ornaments. Of course, hanging one picture is simple. But if you have three or four pictures, each with two hooks on the back, and you want them exactly 6 inches apart, and aligned correctly across your wall? Hang-a-Pic will do just that! Using a very friendly walk-through interface, Hang-a-Pic can tell you exactly where to put your nails (or wall-plugs, etc.) in the wall for each picture or ornament. No more headaches or extra holes in the wall from guessing where the nails should go... All you need is a tape measure and Hang-a-Pic will figure out the rest! It's so easy that a 12 year old child could take four pictures, each with two hooks on the back, and hang them precisely and evenly across a wall the first time! No extra holes, no "oops!!". - New Features added to support hanging a group of pictures (or anything else) with different frame widths, evenly spaced across a wall. For example, say you're hanging 3 pictures and the center picture is wider than the other 2, Hang-a-Pic will now make this an easy task to pinpoint exactly where your nails need to be for each picture! - Now supports as many as 5 pictures (or any thing else you're hanging), and each can be a different width. And they do *not* need to be hung symmetrically! - Send measurements to your Email address. - Print the measurements to your AirPrint compatible Printer. - Performance enhancements. PLEASE NOTE: Hang-a-Pic does not calculate how high you wish to hang pictures, mirrors, etc.. Some prefer staggering the height of each picture, some prefer hanging them all the same height. The height you wish to hang pictures is your particular visual preference. For example, do want them at eye-level or higher up on a wall with very tall ceilings? etc.. It's up to you. Hang-a-Pic will however, calculate perfect spacing between those pictures horizontally.
