The problem was there previously since the skin change but is now more frequent.

Also notice that images in some posts have changed :

None of the post data has changed with the recent site updates. I've had a look in that thread and both of the images posted in there are hosted on an external site: "www.snowmediazone.com/the_zone/". Given the thread is 3 years old, it's possible that the image data on that remote server has changed?
