I wanted a reasonably sized photographic image with a 24-bit alpha channel. So I used a JPEG for what JPEGs are good for and a PNG for what PNGs are good for… I combined them using an HTML5 canvas element and then inserted into the DOM. The results look the same as using a normal 24-bit PNG but are one-half to one-sixth the size. In one case we got a 573KB 24-bit PNG down to a 49KB JPEG with a 4KB

The most popular coding language for the web is javascript; so much so that since the advent of HTML5, it has now been officially accepted as the default standard. Javascript has moved beyond a smaller client-side browser-based language to become integrated not just for front-end design, but also for back-end server-side development. As a result there are has been a huge growth of Javascript libra

loupe.js (photorealistic loupe effect for images)
loupe.js 2.0 allows you to add photorealistic loupes (magnifier) to images on your webpages. The design is changeable by use of an image editing program. It uses unobtrusive javascript to keep your code clean. It works in all the major browsers - Mozilla Firefox 1.5+, Opera 9+, Safari, Chrome and IE6+. On older browsers, it'll degrade and your visitors won't notice a thing.
