How to Bind a Payload to an Image as 1 File !

Hello guys i want to ask you how i can bind a payload created by veil-evasion to an image ( .jpg ) . i saw a video on youtube that it uses the cmd on windows to bind the payload with an image with the following command ( copy /b payload.exe + payload.jpg payload.jpg )

I tried it but with no session :/ . I also know the other method with batch file but i don't prefer it . I want the victim to see just an image and when it opens it ... Kaboom ! :)
