HiSRCUsa JavaScript com jQuery, semântico, testa bandwidth, requer markup extra na tag <img>https://github.com/teleject/hisrc

Adaptive ImagesServer-side, usa .htaccess e PHPhttp://code.google.com/p/css3-mediaqueries-js/

PicturefillUsa JavaScript, segue a proposta mais aceita entre developers sobre Responsive Images (tag <picture>)https://github.com/scottjehl/picturefill

OutrosO Chris Coyier, do CSS-Tricks, fez um excelente comparativo entre as diferentes técnicas (link em inglês)http://css-tricks.com/which-responsive-images-solution-should-you-use/

Nenhuma Media Query funciona no IE6–8 sem plugin. =/
