HTML DTD

Hi everybody,
We are using the Validator to validate our Html files.
we would  like to specify every time we use an image Tag
(<img ....> or <input type=image ...>) the height and the width
of the image. That allows the browser to download images faster.
So how I can do to REQUIRE the width and the height for the tag INPUT
when the type is IMAGE  :

<INPUT type=IMAGE width=33 height=40.....

Any suggestions ??
