Padlocks On Photos On Old Login, New Login Cannot View Photos At All

I've been using my parents computer for the last few months and decided to make my own user/log-in the other day. After doing so, I cut/pasted my photos folder into my new user directory (or whatever, I'm not very techie..). I have thousands of photos, my BF is a photographer, and I can view most of them. However, in one particular folder 90% of them aren't viewable! Says I don't have permission... When I log back into parents windows, I can see the photos in my directory (as they are no longer located in theirs) but there are little gold padlocks on the ones I cannot see on my log-in. I've tried changing permissions, ownership, you name it.. I've looked for help on line and tried everything. The only thing that seems to work is if I right click on each individual photo and change things that way.
