Aligning picture under a centered one?

[Shnitzel]

Hey,
I started learning some HTMl lately and came across a problem.
I have two pictures. One is centered at the top of the page, while the second should be directly below it and to the left.
I have attached an illustration.

I got the text aligned to the right of the side picture, but the side picture is tight with the left side of the window, while it needs to be tight to the left position of the top picture.

Is it even possible?
If it is, any help is very much appreciated.

Thank you in advance.
