@xPedro, I agree with you. The following domains are a good idea to be added, replacing Tinypic, https://imgur.com https://postimages.org/
@Maverick, I believe https://photobucket.com/ should be considered as well as it will be replacing Tinypic, as their welcoming banner states. However, though, some xat users wouldn't want their public photobucket profile to be accessible due to exposing personal information. This could be an "under consideration" idea.
