Well I looked at the web page and the first thing that jumps out at you is there is no different in the images??? If its scaled then it should be LARGER, right?

An old Photoshop trick is to upsample in steps rather than all at once. Not good for a MPEG, but if you're staring with a lossless file type. upsize in 10% steps. In other words version #2 is 110% of the original's size. Version #3 is 110% of version #2 and so on.

If you try to jump say 150% all in one step, results usually are inferior. There is software that specializes in this kind of thing.

After looking at the software and its algorithm, it does not appear that it would be well suited to photographs, only "cartoon style" drawings. I downloaded it to play with it anyway.

Right. You should have looked harder. The images ARE larger. They normalized them for the comparison.

Especially fractal expansion. Works great for prints and no need for the incremental steps.

I concur. I was able to duplicate the great results on their cartoon examples. However, it does nothing for larger and more complex images. I also tried it on some simple pngs, e.g.,the DVDA icons. No benefit there, either. Oh well.
