Facebook "LIKE" button.

[Tantirx]

Hi all;

I have setup a "like" button to show up on every product page in my store. I did this by inserting the following code into my includes\templates\MY_TEMPLATE\templates\tpl_product_info_display.php file

<!--bof Facebook LIKE button -->
<P ALIGN=center><iframe src="http://www.facebook.com/plugins/like.php?href=<?php echo urlencode(zen_href_link(zen_get_info_page((int)$_GET['products_id']),'cPath='.(int)$_GET['cPath'].'&products_id=' . (int)$_GET['products_id'])); ?>&amp;layout=standard&amp;show_faces=false&amp;width=450&amp;action=like&amp;colorscheme=light" scrolling="no" frameborder="0" allowTransparency="true" style="border:none; overflow:hidden; width:200px; height:40px;"></iframe> </p>
<!--eof Facebook LIKE button -->

Now; the button works well but....when I click like on a product page and then go back to my Facebook page the Product info shows up fine but the product pic is not shown....quite on the contrary another seemingly random graphic from the product page is visible on the Facebook page.

How can I get the actual product image to show up in Facebook and not incorrect graphics? Please feel free to fo to the site and click on "LIKE"...then go to your facebook page and see what I mean. The URL is http://oceanabyssaquatics.ca/store/

Thanks in advance for you assistance
