I am planning to put a about 4X5 size picture on my website as a background. I would like to have it fit perfectly on the page and I want to make sure that the website will fit in any monitor with any resolution. I am using a 19" monitor and with 800X600 or 1024X786. I want to make sure that the background picture will not need to stretch or tile on any screen. What can I do about it.
