CPU/RAM server issues with images?

[webdev]

Hi, all. Does it use more server CPU or RAM if your site images call for the full URL's (like http://www.yoursite.com/folder/another_folder/image.jpg), rather than just "../image.jpeg"? My webhost (Lunarpages) is incessantly complaining that my images are using more than 2% server CPU/RAM,...

I don't think that images can cause a lot of CPU usage. Heavy visitors on your site will do that for you.
