The option to miniature pictures in a nice row when sending more than one.

Right now when you wanna upload or show more than one picture or image it will upload each imagine in a new row. 
The idea is to keep the old system but also get the option to be able to miniature all of the picture in a nice row instead of sending them one by one after each other.

Uses would be for example in a community server, if you make a post with some text and then miniature picture right under it in a nice row, instead of having to scroll up in order to see the whole post cause the pictures are just spammed under each other in a new row.
