I have done many small programming gigs for random people I met online. Now, I want to use their websites in my portfolio.
I know the safest answer would be "just ask for consent first". However, I am no longer in touch with these people and emailing them would be very embarrassing due to some personal reasons.
This is my plan:
Go to their websites, take screenshots of the respective homepages and post those images on my website along with their url's.
I'll mark it simply as "projects I have contributed to". I was also going to mention what exactly I contributed to the project, but maybe these people don't want that information public.
Again, I know the safest answer is "just ask". However, I just want to know what all I can post legally on my website without getting in trouble. (Obviously, I did not sign NDA or have any informal NDA, otherwise I would not be asking this question.)
