Progress Bar Issue (using Onloadstart, Onloadend, Onloadprogress)

HTML code:

Loading

Solution 1:

You are trying to use onloadstart and onloadend on the img element. These are what are known as progress events.

Progress events are currently only valid on video and audio HTML elements. They are not valid on img elements.

Solution 2:

onloadstart and onloadend supported only audio and video tags - http://www.w3schools.com/tags/av_event_loadstart.asp
