Hello. I knew you have edited the Template:Episode. I have the question to tell for you, I hope you agree my propose to this template.
I will change this template from show 1 image to show 2 image: one thing for show image which capted title the episode, the other things show image which capted a screen from this episode and they will be used tabber.
For screenshots from the episode showing events of that episode, those are usually shown in a gallery within the article synopsis, or adjacent to the description of the relevant scenes within the synopsis (if it's long enough).
I think the suggestion is basically that we have title card screenshots in the infobox, in a similar vein to Wikimon. I have wondered if we should do something similar, my only reluctance being that the early English dub title cards are kind of bland and uninformative.
