Some of the pictures I find in other galleries on the wiki (like episode or character). I'll also go through the crew's social media to find pictures that haven't been uploaded to the wiki, and if that's the case, I will do that.
Seems like it was just a bug. It looks like when you edited the page it converted all of the existing punctuations on the page into their ASCII formats? No idea why that would happen but watch out for it in the future
