i just want to put a picture in a picture and it keeps sending me to all these  tutorials. how do i just do my picture

Well, Photoshop is the 747 of image editors. You have to take the time to learn it.

So you open the two pictures.  Picture 1 and Picture 2

Then use the Window menu > Arrange > 2 up vertical to see both pics.

Click on the Picture 1  Look at its' Layer panel, and drag its' layer over to picture 2 and release your mouse button.

Picture 2 should have Picture 1 added in.

That's one way to do it.
