“Seam carving” is an image resizing algorithm developed by Shai Avidan and Ariel Shamir. This algorithm alters the dimensions of an image not by scaling or cropping, but rather by intelligently removing (or adding) pixels from the image that carry little importance. The importance of a pixel is generally measured by its contrast when compared with its neighbor pixels.

Rsizr is a new Flash based photo editing site wich uses “seam carving” algorithm and there’s also a plugin available for GIMP.
