There is no questions that full screen images are appearing everywhere on the web. Bigger is better in 2010. Widely available technology is utilized to create visually impacting large background sites.
Some large background sites rely on a fluid layout to stretch out across the browser viewport and other use large images with a static size to create large backgrounds. But, you don’t want to stretch an image without distorting the aspect ratio. There are solutions to this problem that allow you to produce large image backgrounds.
The easiest way to stretch any background image is to use a background image in CSS. Use a background image with the same or more pixels than the sample file so the image won’t get pixilated. Faster Internet speed and increased resolution in monitors lets us push the limits and create backgrounds that used to be impossible.
