The above image is a snippet of a picture I took while snorkeling in Hawaii last week. If you right click on it, you will notice a conspicuous lack of image-related commands. No “Save image as” or “Copy image.” This is because it is not an image. It is an HTML table with cells 1 pixel wide and 1 pixel high and all the background colors of the rainbow. The size of the HTML is much larger than the original image and it grows proportional to the total number of pixels in the image with no compression whatsoever. So, why would anyone ever want to do this?
