The interesting thing is :
1. Sometimes it opens; however, when I repeat opening other images it breaks.
2. When I select many file and open their thumbnails (C-t d) and then
open the thumbnail, it does not break!
3. I use helm; so when I do C-x C-f and then C-downarrow on an image it
shows as well.
So, the problem is only when I open right to the buffer!!
