Sprite Cow helps you get the background-position, width and height of sprites within a spritesheet as a nice bit of copyable css. I personally found it pretty useful and easy to use.

There are one or two rather clever tricks happening with Javascript and Canvas to discover the dimensions of images and generate the CSS, they have also shared the code on Github so that others can see under the hood.

Adding relevant images to static prototypes is a pain, that is why folks tend to fill them in with placeholders. If you really want to add an image, you have to search for it, download it, crop it to right size, and then add it to your prototype. That is until now.

flickrBomb is an easy way for you to fill your prototypes with relevant content, and not just those dull gray placeholder images. Hover over the images and click the wrench icon to see flickrBomb in action.

Kilian Valkhof came across a website that had a whole slew of JavaScript that attempted to prevent you from selecting text, right clicking or dragging any content onto your desktop.

So he decided to copy the JavaScript and create a library with examples of JavaScript techniques you can use if you want to scare your visitors away, or want to piss them off. Annoying.js is the result.

As you can see, you can do some pretty bad things with Annoying.js that will certainly drive your visitors away. However, some functions is actually very useful if you’re writing complex “html5″ web applications. By disabling text-selection on interface elements you can make the application easier to use, and you can re-implement the right click menu using your own options.
