Most web sites have images on then but the actual image size is not embedded within the HTML document itself.
I noticed that because I always enter the text I am looking for in the search box and jump directly to the section of the page I want to read, the problem is that always the current position changes by several scroll steps while each image loads independently of the html document.
Heck!... it’s like trying to read the newspaper directly from the printing machine.
I know that the HTML tag has the height and width fields, that are used for the browser to construct the page layout, but most web designers don’t use them.
