html - Reduce loading time of heavy images in html5 -

-

i trying load heavy ong images in website. have tried use photoshop -> posterize method reduce file size of heavy pngs followed online tools reduce png file size without major compromizing filesize of image. have als tried pre-loading images, still taking considerable amount of time load.

can please suggest me way reduce loading time of png images on website, they load quick?

many in advance!

even if follow all/some of the previous advice, nice addon workflow passing pngs through pngoptimizer.

it's simple drag , drop program strips unnecessary information out of pngs. depending of type of image, size saving varies between 5-10% , more 70%.
