ImageResolver.js

ImageResolver.js does its best to determine the main image on a URL without loading all images.

Demo : http://mauricesvay.github.com/ImageResolver/

Works without any extra request with:

  • image URLs
  • imgur.com photo pages
  • 9gag
  • Instagram

Works with an additional request:

  • imgur.com album pages
  • flickr.com photo pages (requires an API key)
  • any other webpage with Opengraph tags (requires a proxy)
  • any other webpage by looking at <img> tags (requires a proxy)

ImageResolvers.js compatibility can be extended to more sites by writing plugins.

Usage

The API might break in the future.

<script src="ImageResolver.js" type="text/javascript"></script>
<script>
ImageResolver.register(new FileExtensionResolver());
ImageResolver.register(new ImgurPageResolver());
ImageResolver.register(new NineGagResolver());
ImageResolver.register(new InstagramResolver());
ImageResolver.resolve(url, callback);
</script>

Dependencies

I'm working to reduce dependencies, but for now you need:

  • jQuery
  • URI.js
