How to show free shipping icon when product weight is zero?

I would like to show the free shipping icon on the product info page when the weight of the product is "0".
All Products are marked as:
Always Free Shipping NO

Shipping/Packaging I have chosen 0 weight does NOT mean Free shipping ...

I have the following shipping modules turned on:
Zones
Free Shipping Options freeoptions
I have set the total >= 0.00

How do I change the code to show the shipping icon when the product weight is "0"?
I have looked at a similar thread but here Ajeh forced the shipping icon to show on all product info pages.

Ajeh:

Okay ... this is very different ... :unsure:

If you want to see the Free Shipping icon, you need to force that by modifying the IF in the tpl_product_info_display.php ...

Copy that to your templates and overrides directory and edit this section:

Change the IF condition to check the Product's Weight and if 0, then the Free Shipping icon will show ...

You should be able to use:
$products_weight

Note: if you also use attribute weight then you will need to consider how you want to manage this for attributes that might add weight to a 0 weight product ...

Thanks Ajeh,
I have tried the following code but it works the other way around; the freeshipping icon is showing up on products that weigh over 0 .
Can you help me out?

<!--bof free ship icon when weight is 0 --> <?php if ($products_weight !=0) { ?> <div id="freeShippingIcon"><?php echo TEXT_PRODUCT_FREE_SHIPPING_ICON; ?></div> <?php } ?> <!--eof free ship icon when weight is 0 -->

You're asking to show the icon when the weight is NOT 0

You need to change it as follows:

<?php if ($products_weight ==0) { ?>

Thanks a lot Clyde, that did the job. Zen Cart rocks...
