The graphic file Bob.jpg is in a folder called 'graphics'. The height, width and "alt" are optional. The inclusion of the height and width (in pixels) will cause the picture to load faster by preventing the browser from needing to do calculations to determine how the page layout will need to be, which it can't do until the picture is done loading. The "alt" is text that will exist where the picture would be, in the event that for any reason the picture can't load (such as browser incompatibility).
The above can be placed inside of the following tags to position the image on the page. Different browsers decode this part differently, so be sure to try your page on a variety of browsers to be safe.

Here's the tag syntax:
Here's an actual example:
