If you've ever taken pictures of a great house, but there was just one or two things that ruined the picture—like a crack or stain--WebInpaint can help. WebInpaint is the free, web-based version of Inpaint, a paid application that removes flaws from photos. Normally, Adobe's $600 image-editor, Photoshop, would be used for such tasks, but WebInpaint is free, and doesn't required graduating with a community college degree in graphic design to used.
But free also means imperfect. WebInpaint can't remove major flaws (it probably won't fix a shattered window or greasy stovetop), but you can probably remove weeds or driveway oil stains from outdoor pictures, and maybe some kids' toys from a playroom. Remember to be honest, though. If you remove that oil stain from the photo, make sure you actually remove it before you show the house.
To use WebInpaint, upload your flawed image, paint over the flaws with your mouse (you can adjust the brush size to be smaller for finer detail), then press the Inpaint button. The most important thing to remember is paint small areas, and "Inpaint" often. Don't paint over every flaw, then press Inpaint once. You'll want to make one or two strokes with the brush, then Inpaint, repeat, and repeat. You'll probably want to Inpaint over things you've already "Inpainted" until it looks right (or as close as you can get to "right"). Unfortunately, there's no Undo feature, so if you really mess up, you'll need to upload your photo again, and start over. With a little practice, you'll figure it out.
Whether or not it works on wrinkles is yet to be tested.
