Imagine Picture Viewer is a lightweight alternative to the default Image Viewer in Windows, that adds a few basic editing tools.
With Imagine Picture Viewer you can browse images on your computer without the bloat of bigger graphic suites. The program features also a bunch of tools to do basic editing tasks, such as resizing, cropping, adjusting brightness and contrast, flipping and rotating.
Imagine Picture Viewer also includes a few simple effects to give your photo an original touch. You can turn the selected image into black and white, apply a shade of sepia to it, or even make it look like an oil painting. And when you're finished editing the image, you can share it on Flickr, Picasa, Twitpic and ImageShack from within the program.
That said, you should take into account that Imagine Picture Viewer has some limitations: it only lets you undo the last action and is a bit slow when editing large images – but it's still better than Windows' default viewer, in any case.
With Imagine Picture Viewer you have not only a lightweight viewer for your photos, but also a handy app to do basic photo editing tasks
