imgzr

imgzr, a jQuery responsive image plugin

  • Update: february 24, 2012 : changing the img source only when needed.
  • Update: january 17, 2012 : now with REAL screen orientation detection and browser resize.
  • Update: january 13, 2012 : now with screen orientation detection.

how to use

Include :

  • jquery.
  • Include jquery smartresize
  • Include the imgzr.js file.

And call:

$(function () {
  $('body').imgzr();
});

It will look into the given element (here "body") for image and change the src if needed. Check the demo (broken link) (last version is v0.3.1)It has been tested under :

  • Chrome 16
  • Firefox 9
  • IE9
  • Ipad
  • Iphone

There's a weird thing happening on my Android 2.3.5 (strange behaviour about screen orientation), but I hope to make it work soon !

configuration

Prepare your images ! Your image should have the small image in src to prevent bandwith overcharging. Add data- with the well sized image. Example :

  • src="./img/small.jpg" alt=""
  • data-small="./img/small.jpg"
  • data-medium="./img/medium.jpg"
  • data-large="./img/large.jpg"

The default configuration is the following :

resolutions:{
  small:{min:0, max:480},
  medium:{min:480, max:768},
  large:{min:768, max:10000}
}

You can change this passing a new configuration to the function call :

$(function () {
  var config = {
    resolutions:{
      small:{min:0, max:1000},
      medium:{min:1000, max:10000},
      large:{min:10000, max:100000}
    }
  };
  $('body').imgzr(config);
});
