I've just installed the Facebook OpenGraph plug-in from this forum, and it blows up on getting the image. I went back to the original code for it and found that the line
$myImage= zen_get_products_medium_image((int)$_GET['products_id']);
works if I change it back to the original variable name, which was zen_get_products_image
So it's working. But the image it displays is the original larger one for the product, not the zencart thumbnail. I've gone as far with this as I have time for right now. Does anyone know if there is a way to use the zencart thumbnail instead? I think I could take care of the problem by substituting the actual thumbnails for the uploaded product images, or by manually resizing all the images. But that would take hours that I don't have.
