A user encountered an issue where product page links shared on WhatsApp and Facebook Messenger displayed no preview image, though Facebook wall posts showed images correctly.
Root Cause:
The problem stemmed from the og:image property code in the theme.liquid file.
Solution Implemented:
WhatsApp-Specific Constraint:
The WhatsApp issue had a different cause—WhatsApp requires preview images to be under 300KB in file size. Once the user reduced their product images below this threshold, WhatsApp previews began working.
Status: Resolved. Both Facebook Messenger and WhatsApp now display product images correctly when links are shared.
When a product page is shared on WhatsApp or Facebook Messenger, there is no image in the link.
However, the image is displayed when I share the link on Facebook on my wall.
For example, when I share https://veganwear.shop/products/clover-vegan-t-shirt, this is what I get:
Facebook wall - OK:
Facebook Messenger - no image:
WhatsApp - no Image:
The code for the og:image property lives in theme.liquid:
Any ideas?
Thanks! I’ve changed the code as you suggested, but no change.
It’s working @D666 ,
You can’t try on the same device because of caching. You probably need to try tomorrow.
@ThePrimeWeb Your suggestion sorted out the issue for Facebook Messenger. 
But the issue for WhatsApp was something else: the image that WhatsApp tries to fetch for the link preview must be under 300kB.
Thank you again for your help.
