Images upload but do not load when post is published – after moving/copying WP t

My webhost helped me move my WP files to my main directory today.

Since the move, I can post but the images won’t load even though the uploads have been going through okay.

I am using Atahualpa 3.4.5 as my theme.

I have looked through all the scripts that I can see in the dashboard but can’t see anything which indicates where the pics are going to. The url which is generated after the upload is completed points to the old directory and I tried adding a new folder through cPanel but it didn’t work – I don’t know what to do!

thanks
