What is the proper/best syntax to use if I want to use an image for my Submit button on a Form?


Standard Way:
Code HTML4Strict:
<input type="submit" name="addComment" id="addComment" value="Add a Comment"/>


My Way:
Code HTML4Strict:
<a href="<?php echo WEB_ROOT . 'add_comment2.php' ?>">
	<img src="<?php echo WEB_ROOT . 'buttons/AddAComment3.png' ?>" alt="Add a Comment" />
</a>


Someone's Suggested Way:
Code HTML4Strict:
<input type="image" src="<?php echo WEB_ROOT . 'buttons/AddAComment3.png' ?>" />
