When a page has an In-Use template you are to not add any episode images, unless they are storyboards or Post Production ones as well. If you need to edit for whatever reason please contact the user in charge of the gallery.
Furthermore we have guidelines for images.
They must follow the name protocol of Season and Episode being listed.
I tried to make picture for [[The Spokes Family]]. I tried to make it transparent background but I didn't know how. I tried to keep proportions between the characters. Do you think this pic is good enough or needs some improvements?
