Increasing the size does not increase the quality: if the source is crap, the quality is crap too
Also, I guess it was rejected probably because instead of just posting the capture of the scene you include all what is around it: IMCDb does not need to have the interface of the ipad player Why didn't you post it with just the picture like you did earlier here above?

The episode format is also not right: we use "xx.yy" for series.episode, not "SxxEyy"
