I wanted to ask the Arrow wiki community about something. A lot of the pages have profiles pictures that are dark, or in bad lighting where it is hard to see the character's face or physical features. (i.e.Malcolm Merlyn, Slade Wilson, and somewhat of Oliver Queen). I wanted to know what the rules are for changing a character's profile picture, and if it would be okay if I changed some of the pictures to better quality photos. I would be more than willing to search for higher quality photos.
Thanks for your time and reading this!
