Plugin Not Posting Complete Image

Sir, I am primium user.
One of the problem,I faced is that it didn’t post full image instead it cuts image from outside during posting on Facebook. I haven’t check it on any other social sites.
I also try to use the feature of text post with image. In that also, Image is not fully posted, some area of image was missed when I checked on FB after posting.
I want to post full image as is uploaded on my blog.
Kindly take a look into this matter.
No error is being shown.
Everything works fine instead of this issue.
Kindly solve the problem as soon as possible.
Thanks in advance
