7. Images <img>
<img src=“URL/filename.jpg”
alt=“Caption image”
width=“300px” height=“400px”
title=“Show text when mouse
over”
align=“right”
border=“10px”/>

8. Images with CSS
div.Img {
Margin:2px;
Border:2px solid #0000FF;
Height:auto;
Width:auto;
Float:left;
Text-align:center;
}
<div class=“img”>
<a target=“_blank”
href=
“http://www.google.com”>
<img src=“google.jpg”
alt=“google logo”
</a>
Add a description of the
image here
</div>

9. Images with CSS
img { Opacity is transparency
opacity: 0.4;
filter: alpha(opacity=40);}
img:hover {
opacity: 1.0;
filter:
alpha(opacity=100);}
IE9, Firefox, Chrome, Opera, and Safari use the
property opacity for transparency. The opacity property can
take a value from 0.0 - 1.0. A lower value makes the element
more transparent. IE8 and earlier
use filter:alpha(opacity=x). The x can take a value from 0 -
100. A lower value makes the element more transparent.
