Not sure if this will help get it fixed or not, but here is something i noticed:

On August 25th I posted a pic and it is still the thumbnail of what it is supposed to be (in my own personal page of images), the next one I posted was September 15th, and that pic is sharing the same new image as everything I posted post-9/15.

So, I think the glitch had to occur after 8/26, because my August 25th pic and all previous pics are what they are supposed to be.
