Ok so you want to add a image to a HTML document, heres how you do it.
<img src="URL OF IMAGE"> <img src="http://www.google.com/intl/en_ALL/images/logo.gif">
This would produce this:
More advanced things include
alt, border, height, and width.
<img src="http://www.google.com/intl/en_ALL/images/logo.gif" alt="Google's Logo" border="2" height="30" width="30">
That would make this, because the height and width is 30 it is a 30×30 image.
The alt makes the scroll over text appear (when you scroll your mouse over the image).
The border is the amount of border the border when it’s is a link (default is 2).
