FastStone Image Viewer

Programs such as Photoshop offer a full-fledged workshop for editing and creating images, but they're too powerful, complicated, and expensive for casual photographers. True to its name, this intuitive program does indeed let you view your pics, but it also does much more. For starters, it can convert and rename images in batches--a handy, timesaving feature. It also provides a decent set of basic editing tools, including those for cropping, rotating, removing red-eye, and adjusting brightness, color, and contrast. FastStone Image Viewer can even display your photos as a slide show, complete with your favorite songs. There's a lot to like here, and nothing to pay.
