Background of what? Windows desktop? Web site? Android phone? HTML table?

If you are talking about WEB design, then you can calculate how fast an image will load by simple equation:
Image size in MBytes (500kB =0,5 MB) multipied by 8 (to get bits) = 4 Mb
If receiving side has 4Mbits per second internet connection, this image will load approx. 1 second. This is the impact in performance.

Oups...submitted to fast.
Here's what I also wanted to add: some web site speed load testing tools online:
http://www.linkvendor.com/seo-tools/speedtester.html (you can see SIZES and loading times here)
http://www.websiteoptimization.com/services/analyze/

In general, for web design images should not exceed few 100kB in size. Optimize larger images by:
- reducing color palette
- compressing JPEG
- if you are using PhotoShop you have "Save For Web..." option, where you can see both, final image PREVIEW and SIZE prior to saving in different format or with different palettes and compression levels
