Why won't my images appear inside buttons? In the page displayed, there is a row of buttons that each say "Submit Query."



The HTML for one of these buttons is:

&lt;INPUT TYPE="image" SRC="../images/OneLine30px.png" CLASS="select-button" ID="OneLine"&gt;`


I've also tried slightly modifying the paths to these images. This HTML is in a .tpl.php file which is inside the templates directory. The images directory is a sibling of the templates directory. 


Why is Drupal displaying "Submit Query" instead of the image?
How can I get Drupal to display the images?
I'd strongly advise to use CSS for this, it's much more easier to apply and you won't hit path related issues.
