The jQuery Retina Display plugin will substitute high resolution versions of your images (if they exist) for high resolution displays (such as iPhone 4) only.
This plugins requires no client-side changes, other than the inclusion and initialisation of this plugin. If the 2x image doesn’t exist, the standard resolution image is displayed.
Try the demo on your iPhone 4 and switch between the hi-res and low-res images. Here’s the shortened URL: http://drp.ly/1BNu3R
Note pour plus tard, si besoin.
