Well, with Mathematica 7.0 this is really straightforward since V7 many 
new function specially designed for image processing [1]. For instance,

    img = Import["ExampleData/rose.gif"]
    ImageResize[img, {200, 600}]

You could check the Wolfram Demonstrations Project, which contains many 
applications about image processing, though quite a lot of them seems t 
use extensively Mathematica V7's new features [2].
