HTML Attribute for <IMG ...>
SRC ="text string"

SRC tells where to get the picture that should be put on the page. SRC is the one required attribute for <IMG ...>. For example, suppose that the GIF file "../graphics/pumpkin.gif" is in the same directory as this page. We can place it in the page like this:

This Code Makes This 
<IMGSRC="/graphics/pumpkin.gif" ALT="pumpkin">
pumpkin

SRC is a hypertext reference, like the <A HREF="..."> attribute. The reference can be relative (like the example above) or it can be a "fully qualified" reference.

<IMG ALT="..."> >
