Product image is not coming when sharing on facebook

when i share product the image is not appearing, is there any solution!

My recommendation would be to add the following code to the header.tpl file , located at catalog\view\theme\YOUR_THEME\template\common\header.tpl

Search for this code... Add this below it... This should only add the appropriate metatag if you're on a product page (where an appropriate thumbnail is available). Depending on your theme, you should be aware of this note...

Please use an image that's at least 200x200 and preferably 1500x1500.

...default for OpenCart is above 200x200, but you may need to adjust as appropriate.

thanks bro for the reply, but still it's not working, any other solution?
