Changed domain name problem

Hi!
So I just wanted to change my domain name form nailnaljaks.ee to parimad.ee and I asked my web host to do it. Now He changed it (i think he added the same hosting to parimad.ee from nalinaljaks.ee right?)
But now, when i go to my site parimad.ee (before nalinaljaks.ee) and click on pictures, then they wont open (try it by yoursef).

Also I don’t know how to accsess to my sit form wordpress. Usually I Logged on form nalinaljaks.ee/wp-admin, but now i do not have parimad.ee/wp-admin.

Im sorry, my English is not one of my sharpest tools, but I’ll hope that you’ll get the point.

If you know what to do to get verything back to nrmal (login, adding pictures etc.) then please tell me step by step. It’s quite new for me.

Thank you!
