Captive Portal input button - submit vs image

[glstud]

Is there any way to add an input button that uses an image source rather than the standard form button?  This slight change to an unauthenticated login works fine with the vanilla button, but using an image input type breaks the submit process it seems…

<form method="post" action="$PORTAL_ACTION$"><input<br>name="redirurl" value="$PORTAL_REDIRURL$" type="hidden"> <input<br>name="accept" src="captiveportal-acceptbutton.png" type="image">

thx!</input<br></input<br></form>

Try applying a style to the button, instead of replacing it.
