Here’s an example on Twitter where I’ve uploaded an image and I have my content, and I almost ran out of characters, but I wanted to include a person that was actually in this YouTube video that I’m promoting. And the only way I was able to do it was by tagging them in the picture.
The way you do it is just go to your Twitter and click on the camera picture. Go ahead and grab any picture that you like and then go ahead and say, “Hey, who’s in this photo?” And you can start adding people to the photo.
You can add a total of 10 people to a photo at a time and they’ll automatically be part of your Tweet without taking up any of the characters. Now, key thing is don’t go randomly tagging people that aren’t relevant. They should be part of your post.
