I'm using the variable $product_image in this html code. I'm not sure why it's not displaying the image. When I echo the variable, I get the value gano_logo_1.jpg. When I type in gano_logo_1.jpg in the html code, it displays properly. When I check the source code of the page after it's run the src='' is blank.
<img border='0' src='$product_image' alt='$title' width='175' height='116'></td>
