Best Practices for Reduced Image Size on WordPress

  • Background images should be no greater than 200 K
  • Try to keep other web images under 50 K
  • Avoid PNGs when possible
  • Yahoo’s is a great tool for reducing image size.

Also saving images as progressive jpegs results in a smaller image & the browser progressively loads the images which is muy bueno for UX
