Request Can anyone combine these images?

All I basically need is them to be right next to each other and the exact same size. I've been resizing the same pictures but they always come out differently. I've even attempted to copy/paste and one always covered up the other.

I need the American Flag and Spanish flag next to each other and the same exact size. That is all

Just next to each other? If that's it, I can do it. What sizes do you want them?
And you want the American on the left?
