If you can add in your own html you can have an img tag next to the image and set the src to the button image. If you place a link around this you should be able to link to the detail page the same way the image does.
<a href="http://google.com">
<img src="your buttom image.jpg"/>
</a>
If you are unable to edit the html around the image then it might not be possible to add this in.
