Automated resize of background image
 

Hi all,

I have a problem with the bg image I placed in my blog site and I don't know how to resolve it. I created an image in resolution 1400x1050 that of course is perfect for my pc resolution. The problem is that the bg image is a totally mesh when the web site is visualized in other pc with lower resolution like 1024x768. Do you know if there is any solution in CSS or HTML that I can use to solve this problem?

Thank you in advance for your help!
