HTML <input> height Attribute
Define an image as the submit button, with height and width attributes:
First name: <input type="text" name="fname"><br>
Last name: <input type="text" name="lname"><br>
<input type="image" src="img_submit.gif" alt="Submit" width="48" height="48">

The height attribute is supported in all major browsers.
Definition and Usage
The height attribute specifies the height of the <input> element.
Note: The height attribute is used only with <input type="image">.
Tip: Always specify both the height and width attributes for images. If height and width are set, the space required for the image is reserved when the page is loaded. However, without these attributes, the browser does not know the size of the image, and cannot reserve the appropriate space to it. The effect will be that the page layout will change during loading (while the images load).
