What size to use for background image?

Because of the different monitor sizes and settings, I was wondering if there’s a rule of thumb when it comes to the size of a background image. I want it to most, if not all, fit an entire screen of visitors’ monitor.

I’m working on 1024x768 setting, but I know my imac at home uses a different setting, any guidelines or suggestions I can follow to ensure that my background image is seen properly by different resolutions.

Thanks :slight_smile:
