Facebook like button displaying second image when clicked

[shivneetns]

I have implemented a facebook code and also implemented facebook plugin. Now look in to my page

"http://manutdclothing.com/product.php?id_product=11"

 

See the first image and second IMAGE

 

when i clicked on LIKE button the facebook like button displaying the second image not the first image in from this product gallery.

 

I WANT FACEBOOK TO SHOW 1ST IMAGE WHEN CLICKED ON LIKE BUTTON

 

 

To improve this i test the backend changed the cover image also changed the positions of images in the gallery and i found that what ever image i upload second time the like button is showing only that image

 

LIKE

 

I have uploaded three images

A B C

 

WHEN I CLICK ON LIKE BUTTON THE FACEBOOK PAGE SHOWS "B" IMAGE

 

NOW IF I upload three images IN THE SEQUENCE SHOWN BELOW

B A C

 

NOW WHEN I CLICK ON LIKE BUTTON THE FACEBOOK PAGE SHOWS IMAGE "A"

 

Please help me out to solve this problem.

 

Thanks and Regards...
