Example
Use The Evaluator (Chapter 13 in JavaScript Bible) to experiment with the
height and width properties. Begin retrieving the default values by entering the
following two statements into the top text box:
document.myIMG.height
document.myIMG.width
Increase the height of the image from its default 90 to 180:
document.myIMG.height = 180
If you scroll down to the image, you see that the image has scaled in proportion.
Next, exaggerate the width:
document.myIMG.width = 400
View the resulting image.

Example
Use The Evaluator (Chapter 13 in JavaScript Bible) to experiment with the
hspace and vspace properties. Begin by noticing that the image near the bottom of
the page has no margins specified for it and is flush left with the page. Now assign a
horizontal margin spacing of 30 pixels:
document.myIMG.hspace = 30
The image has shifted to the right by 30 pixels. An invisible margin also exists to
the right of the image.
