I just added "You can see message numbers starting client with -N" to the load_photo and the view_photo description.
I've been in trouble because of not knowing how to download files so I think its use-full.
I'm not sure if it's how github works my idea was to Propose this change to the main branch.

Update interface.c to avoid error messages

When hitting enter (without writing anything) in an chat prompt always appears an error message telling you that the message is empty.
Checking the content of the line can avoid this.
I don't know is this behaviour is wrong or right.
So please forgive me if it doesn’t make sense.
