Decker is a multimedia platform for creating and sharing interactive documents, with sound, images, hypertext, and scripted behavior. You can try it in your web browser right now.

The script looks through the page for any images with the class "low", and if found, reveals a button on the page and attaches the image swapping function to it. The function swaps out the source, and doubles the width/height.

The half size low-res image does two things: it greatly reduces the file size, and shows the pixels better (when enlarged by CSS). By using "image-rendering: crisp-edges;" in the CSS, the enlarged pixels are kept sharp.

An extensive, fast, and accurate command-line image dithering tool.
