/**
The JavaScript functions below will gradually enlarge or shrink an image

some other interesting applications of it as well.

you wrote them yourself.

This is the function that should be called in the onMouseOver and onMouseOut
events of an <img> element. For example:

<img src='onesmaller.gif' onMouseOver='resizeImg(this, 150, "onebigger.gif")' onMouseOut='resizeImg(this)'>

The only required parameter is the first one (imgElement), which is a
reference to the <img> element itself. If you're calling from onMousexxx, 
you can just use "this" as the value.

The second parameter specifies how much larger or smaller we should resize
the image to, as a percentage of the original size. In the example above,
we want to resize it to be 150% larger. If this parameter is omitted, we'll
assume you want to resize the image to its original size (100%).

The third parameter can specify another image that should be used as the
image is being resized (it's common for "rollover images" to be similar but
slightly different or more colorful than the base images). If this parameter
is omitted, we'll just resize the existing image.
