How to save a picture from the Internet on the server?

I made a picture upload from a user's PC using Multer. Now it would be necessary to make a download from the Internet using the user's link. And there was a gag how to do it right?
How to do it correctly, what is the procedure, what are the auxiliary bibles for this (or can you get by with one request / axios)?
How can I find out what the link is to the picture?
How to limit file size before uploading?
