567543 I need help to get website displaying correctly

I have migrated a website from one server to another one, using Httrack. (I am taking over management of the site from another web company and they won't provide FTP access, so I had to use Httrack to get it.) I now have the site on my server, working on an IP address, but some images are not showing and some links are not working. It is probably something quite simple but it's not obvious to me, and I have run out of time to figure it out. I just need someone who can find the source of the issues and get everything working.
