Allow up to 5 images to be dragged and dropped in to one-on-one chats and in the timeline. Can be combined with the existing upload button. The upload file dialog has been changed to allow multiple selections. Drag and dropped images adhere to the following rules, with corresponding validations messages:
- Max 5 image
- Image size must be 0.5 MB or less
- File extension must be one of [".png", ".jpg", ".jpeg", ".heif", "tif", ".tiff"]
Drag and drop and uploaded images are now also deduplicated.
