Implement Swiping up on images

[hoshiwara]

This is more a suggestion than a bug, but when we have an image sent to us, and we open it, it would be nice to be able to swipe up to hide it and go back to the chat room 😄

The swipe is used to see all the videos/images in the current chat room.

If you swipe horizontally, yes.

The request is to leave the slideshow when swiping vertically.
