This plugins not support for  Photo contests/ Photo Competitions sir.

Should have been a matter of course, most logically you ask me. They are made by the same developer. Do not be so; If people buy Photo Viewer like Facebook then they may forget to buy Photo contests / Photo Competitions! or the opposite. You'll get fixed so these two plugins work together, most logically.

Photo contest has its photo viewer to display the photos as well.

Yes its tru, if you uinstall Photo Viewer like Facebook, G+ 

It has been fixed and uploaded to sotre, please update it

Ok i wil lock it later, thank you.

And the video in video contests plugin onely load and loud in Video Viewer like Facebook, G+  but show not any video, onely black!
