Facebook problem

Hello

When I click on the button "Like" (Facebook buttok) on my page, for instance a video is on the board of Facebook appears in this video but displays a picture next to a user or a screenshot from another video. How do I do that by clicking "I like it" -> on Facebook to show in the correct content?

Please Help

Best Regards,

Lucas

Hmmm what?  

Ok, I know it can be difficult to understand. Once again, can more clearly:

when I click the "Like" on my website for example video clip... on the wall at facebook.com appears to me such as my user picture website. This is probably not normal right? So...can it be fixed?
