How to add a picture to launch the game
example Minecraft on launche you see Mojang how to add this on ue4 ?
Nobody ? 
This is a very basic question. Create a HUD widget and add an image to it, then add this widget to viewport. If you don’t know how to do this, you should first read the documentation about HUD
The problem is that I did it to see the screen but I wish it adds to the game before launching the menu how?
Do you mean a splash screen?
You can set that by going to Edit > Project Settings > Platforms > Windows
If you want a logo in-game, you can make a simple movie and add it under Edit > Project Settings > Project > Movies.
Or if it’s just a simple image, you can make a map called for example EntryMap, that functions as your startup map, which shows a simple UI with the image, and after a few seconds transitions to the actual menu map.
it’s not splash screen
I can not have me understand when you double click on my games he started and I would like to display an image before the main menu
That’s also in my answer.
Oh yes thank you =)
