Using this technique without due caution will decrease the accessibility of your site for blind visitors. The program does specify alt text for each of the images it produces, but the alt text is useless -- it consists of "image slice 1", "image slice 2", and so on. Anyone who is listening to this page read aloud via a screen reader will have to sit through multiple repetitions of that. It doesn't convey what the image *is*, or why it's in the web page, or any useful information about the image at all.
The same objection holds for Google Images. Google's spider is blind. It can't see the images in your pages; it needs meaningful ALT text in order to index the image properly in its image search.
The HTML could of course be modified to provide more meaningful alt text. Since the images are actually a single image which has been sliced up, it would probably make sense to specify meaningful alt text on the FIRST of the images, and then blank alt text on any subsequent images. So you would have alt text like this:
<img src="slice1.png" alt="A chemical diagram of coffee." />
<img src="slice2.png" alt ="" />
<img src="slice3.png" alt="" />
Screen readers will then read the alt text on the first image, and ignore it on any subsequent images. Keep that in mind if you're planning to use this tool.
