Yeah, you do have to download them, I only uploaded side-by-side comparison pics for the first game so far, the rest can be found in the downloadable folder version (no side-by-side comparisons there though).
The online version's quality is really, REALLY bad, the downloadable version helps you see the differenets much more than the online version does (though the side-by-side folder version's pictures' quality is also very low, that's because it went through about 4 filters, while the original non side-by-side comparisons only went through 1 filter).
