An experiment in clientside responsive imagery

I'm trying to come up with a solution which:

  • Shows content without js
  • Entirely clientside
  • Keeps the media queries in CSS
  • Fast enough to work on resize

However, this solution is dirty as hell, but it works, here's an example.


First, surround your image, or set of images with some dirty-magic script elements:

<script class="responsive-gallery">document.write('<' + '!--')</script><noscript>
	<a href="">
		<img src="" alt="">
</noscript -->

Dirty isn't it? Anyway, then include responsiveGallery.js, and initialise your gallery:

	scriptClass: 'responsive-gallery',
	testClass: 'responsive-test',
	initialSuffix: '_t.jpg',
	suffixes: {
		'1': '_t.jpg',
		'2': '_m.jpg',
		'3': '.jpg'

This will create a test element on the page with class "responsive-test". When that element has a width of 1px, your images will have a suffix of "_t.jpg", when it has a width of 2px, your images will have a suffix of "_m.jpg". As you can see, you can change those to whatever you want.

Then in your CSS:

.responsive-test {
	width: 1px;
@media all and (min-width: 640px) {
	.responsive-test {
		width: 2px;

Ohh it's so dirty. Yum yum.
