How to disable Firefox form generating a thumbnail on the tab when open an image url.

Hello, I have recently installed Firefox 33.1 and noticed that, when I open an image on a new tab, some of them will show a thumbnail of the image I opened on the tab, while others don't. I am wondering, if there is a way to stop Firefox from making these thumbnails? Thanks.

Do you have an example where this is not happening?

Feels like if an image is larger than around 1000 pixel on one side, it won't have a thumbnail. For example:1500*1500, 1362*768 don't have a thumbnail, while 1024*768 do.
