The Twitter microblog service today announced some modifications that promise to make the photos posted more "social".

Photo Marking

According to a post in official blogFrom now on it will be possible to mark up to ten people in a photo. The interesting thing is that even by marking all the people who are in a photo with you, the 140 characters in the message remain available for you to write whatever you want.
The novelty appears in link form, below the photo you selected. Just click "Who's in this photo?" and select your friends.

Upon appointment, a notification will come to you. It is also possible to change in privacy settings who can mark it.

Multiple photos in a single tweet

The other ad refers to the amount of photos you can post on each tweet. Now it is possible to send up to four photos, keeping the 140 characters to the caption, as in the markup. To do this, just select the images to upload, as you do with one. This novelty, however, will only be initially available to iPhone users, but Android or Twitter Web users will be able to view all photos normally.
