Changing the continue button on checkout

The “Continue” button on checkout page (

index.php?dispatch=checkout.checkout) which sends you to the review page in my site is very small CSS button I want to replce it with img gif button. Is there somebody has done it before or know how to do it?

This thread created by Brandon should get you on the right track:


Yes, I viewed the post, but there is not the same case. As there is for “continue shopping” button, but not for “continue” button on the checkout page.

Which tpl should I edit?
