Here's a pretty picture example laurashoe. I would recommend against picking a hard and fast JPEG quality setting. Or, you may be able to get away with less. Images are typically the most bandwidth demanding element of a page and their impact is most often mitigated by resizing them or reducing their quality. Progressive images allow you to provide a more compelling user experience as well as reduce your overall bandwidth and storage footprint.
These images load from top to bottom, rendering each line of pixels in the full quality of the overall image. As a result, blank space may appear on the page until the image is fully downloaded. Progressive images, however, display in their full dimensions at a lower quality resolution, giving the image a blurry or pixelated look.
The ability to create these scans owes to technical details as to how JPEG image data is compressed. The effect of using progressive images is to give end users a sense of the overall picture even if the details are not yet clear. The primary advantage of Progressive images is their ability to convey visual information to end users on slower connections faster than they would otherwise see it.
This effect can create the perception of that the site is more responsive as a whole.
