Xhtml Strict Method For Submit/reset Buttons As An

What's the proper way to handle submit and reset buttons?Using type submit and reset don't allow you to replace the default button with an image, using the type image doesn't allow a button to automatically act like a submit or reset....so far as I know.So How should I do this when I want to use a custom image as the button?Code will be best way to explain, thanks!

This is how i would do it:

<input type="submit" value=" " name="" style="background: url(url/of/image.jpg); width: width of image; height: height of image;"  /> <input type="reset" value=" " name="" style="background: url(url/of/image.jpg); width: width of image; height: height of image;"  />
