trixtah...but this new technique for image-resizing is fucking amazing (link to YouTube demo). Linkie comes from the Guardian Technology blog, which also provides a link to the PDF abstract describing the technique.
The comments crack me up though: "OMG, you won't be able to tell that a picture has been altered!!!1!eleventy!"
As if you've ever been able to tell an image has been altered since photography was invented, n00bz.
(I'm not talking about those of us who know what to look for, btw - and I'm hardly a Photoshop expert, my graphics experience being in the paintbrush and camera days - but those normal punters who still charmingly don't realise that virtually all photos in the media have been altered in some way).

One of the current ways of analysing doctored images is looking for changes in the amount and distribution of noise over different scales. Given that this new method selectively preserves high entropy regions, I imagine it would stand out like a beacon on that test.
