Replacing a search or submit button with an image
Updated on 18-November-2015 at 9:07 AMYou need to change a line in your code that looks like this:
<input class="searchbutton" value="Search" type="submit">
<input name="submit" class="cat_button" src="/images/button.gif" type="image">
Where /images/button.gif is the path to your image.
You can also style your button with just pure CSS and there are a couple of great links below showcasing and explaining how you can do this.

<button></button> Works the same as your input but gives you more options in how you present your button.
