When viewing pictures (jpg, png, tif, ...), the "play" button appears 'sometimes' in the information panel.
It is normal that it appears for video or music file for instance (allows easy preview), but NOT for jpg files.
If you click on it -> nothing happens (of course, you cannot "play" a jpg file).
Steps to Reproduce:
Rem: this doesn't happens every time. I cant say what special action makes this button appears sometimes and some other not...
"play" button should NEVER appear when previewing pictures
