Paint Shop Pro 2020 - How to add an image to another image

I have two images open.

I want to add one image to the other as a layer. 

I can do that but the second image is too big.

I try to find a handle to make the image smaller but there is not handle.

How can I do this please?

I have tried to use the Corel User to User forum with no luck.  I am registered but forgot pwd and does not send email to reset.

I try to register again and it says, email in use.

Why make things so hard.
