html - button image as form input submit button?

Question

<form method="post" action="confirm_login_credentials.php">
    <table>
        <tr>
            <td>User ID:</td>
            <td><input type="text" id="uid"></td>
        </tr>
        <tr>
            <td>Password:</td>
            <td><input type="text" id="pass"></td>
        </tr>
        <tr>
            <td colspan="2" align="right">
                <a href="#"><img src="images/login.jpg"></a>
            </td>
        </tr>
    </table>
</form>

I am using an image in place of a submit button. How can I submit the login details when the user clicks on the login image as a submit button does?

Answer 1

You could use an image submit button:

<input type="image" src="images/login.jpg" alt="Submit Form" />
