Mathematica 7 adds a suite of image processing functions from trivial to highly sophisticated. To apply them to images, you don’t need to use any form of import command or file name references. Just type the command you want to use, then drag and drop the image from your desktop or browser right into the input line.

It’s been possible since Version 6 of Mathematica to embed images directly into lines of code, allowing such stupid code tricks as expanding a polynomial of plots.
But is this really good for anything?

Here’s an undersaturated mandrill, and a command to increase the contrast. When you surround an image with textual input the image is automatically displayed at an icon size, but the input line still contains the full data of the image. That means if you save the notebook containing the input, the image is saved with it: the input line is completely self-contained.
Is that too much contrast? An obvious thing to want is a slider that lets you adjust the contrast. The general-purpose Manipulate command lets you make just about anything interactive, including the contrast parameter in this example.
OK, but you could just do that in Photoshop, right? Oh shush, let’s do something you definitely can’t.
Here’s a clown fish, and a command that breaks it into 40-pixel squares.
By the way, we’re seeing another neat thing about the integration of images with Mathematica’s typeset input/output system. This result isn’t an image, it’s a list of images. Lists are general things in Mathematica, and lists of images are no exception. For example, here are the image patches in reverse order.
And here they are sorted by average pixel value (roughly by brightness):
And here are the images sort
