Is there any benefit to use Progressive image display, these days, for JPG, Gif and PNG?

Should we use progressive image in both condition as a <img> and in css background?

Does all mainstream desktop and mobile browsers support progressive display?

mobiles doesn't have much speed? so is it really usefful for mibile phone

+1  A: 

Progressive display is useful where there is a slow data link. It allows the person viewing the image to get an idea of what it contains with only a little bit of it transmitted. They might choose to abort transmission if it isn't of interest.

I don't know of any important browsers which don't support progressive display.

No—I mean Firefox, SeaMonkey, Chrome, Netscape, Opera, and the last two versions of MSIE.

  1. It's useful for people on dialup, otherwise I don't think it matters.

  2. Yes, they support it.

A: 
  • Immediate, progressive image display
  • Lossless image transfer possible
  • Full true color (no dithering reducing image quality)
  • No blocking and no color falsity on highly compressed images

Progressive display. Gives quickly a good preview for huge depth 3D images or with slow connection.

All the browsers do support this.
