Examples: “Can you send me those pictures?” “I’ll send you these pictures in a little bit” “They sent the pictures last night” “She will send the pictures to everyone tonight” Keep learning!

They essentially mean the same thing but send along emphasizes that you'll send the information soon/not immediately.
