You can set the Facebook thumbnail image in Page Properties -> Meta tags -> Open Graph -> Image

Are you sure the path to the image is correct? Do you a link to the page so we can see?

Oh my God! I figured it out. Last time it let me upload an image for meta graph. But this time i copied the image url and pasted it there and worked like a charm! Thank You Guys!
