Images pasted into Messages get pasted as TIFFs
If I paste images in Messages on my Mac, more often than not, the messages get pasted as TIFFs and fail to send when I am sending an SMS message. If I drag the photo onto the desktop from my browser and then drag it into Messages. then it comes in as a JPEG or PNG and comes through OK. If I copy and paste it comes through as a TIFF and fails.
If I paste into another messaging app such as Signal or Telegram, then it the message comes through as it's original format.
