"Proper" Image Delivery on the Web

James Duncan Davidson - noted photographer and software developer - has played with image delivery for Retina quite a bit. He details much of it on his blog: http://duncandavidson.com/blog/2012/08/retina_ready

Essentially he currently uses Picturefill (https://github.com/scottjehl/picturefill). From Davidsons' blog: "It’s a compact bit of JavaScript which supports a syntax that mimics the Picture Element Proposal. In a nutshell, it uses CSS media queries to sort out the most appropriate image to use out of a set."

Looks promising.

It's funny how they use a Samsung look-alike wireframe for the non-retina display and iPod/iPad for the Retina. I see what you did there Apple...

This was actually the first thing I noticed too.

Lol. I didn't see that until you mentioned it.

Reminds me of the Finder icons for PCs on your network. http://forums.macrumors.com/showthread.php?t=378638

Very passive agressive

I clicked on Substituting Raster Images for Vector Alternatives. I like how they describe different techniques, but use png files to display them.
