Image boards!

for art servers it could be a cool feature to be able to make channels that can display images in a grid similar to websites like Pinterest and attestation, this can allow artists  to share more images and search through channels better to see posted art or commission sheets for example, or could even be used for servers made for a specific art so they can upload their images in a portfolio style format so people can see through their images better.
additionally it could have a feature apart of this board that you can comment on images and make a thread for that image so the channel isn't overflowed with comments
