I am experiencing the same problem with the "sign in" button sending me to the flash variables file...
eg.

I this situation I do not know how to use the tep_href_link() function instead of <?php echo tep_image_submit('button_login.gif', IMAGE_BUTTON_LOGIN); ?>. If it can be done can anyone give me an example?
cheers,
