Foundation Questions

Hi, I'm currently in the process of buying a family friends home, and I was wondering if any of these images would point to any foundation issues. Imgur: The magic of the Internet

Background Info:

House was built in 1978, located in WV. I was told that when it was first constructed the foundation had some problems, but that drainage and braces were added shortly after to correct the issue, after that nothing else has been done. There are no doors rubbing or any issues of that sort, also no water penetration in basement. Thanks for your help!
