How to delete a Broken File ?

Hello again :) I have one more problem. The thing is few months ago I wanted to add gif avatar and gif fanart, but don't know why, when I submitted them they appeared in the spot as broken files, here u can see them, they are both called 'Aaliyah as Zee "Matrix"' and here are the link to see how it looks like:
broken avatar

broken fan art

I can't delete them on my own, coz when I click on them I'm redirecting to Fanpop Home Page, so my question, what should I do to delete this broken files ? I'm sure there is a way... I'll be grateful for helping me :)
