XD I was rather short for once, eh? I typically post such very detailed responses as to why my opinion is what it is, but to me that situation is really simple. Cullen is the type who stands in the background, but yearns to have someone grow close to him and accept him for who he is and what life he has led. If he has fallen so madly in love with the IQ as it seems he has, well, I don't see why he wouldn't move into the IQ's room or at least stay the night. He has nightmares and I have a feeling that she is one of the few things that sooth them or at least brings him comfort when he awakes.
I can see that. But then I am easily swayed when it comes to getting Cullen in the Inquisitor's bed 
No, it isn't. It's a screenshot from a game. Read the law referring to legal copyright and intellectual property.
If the player does not wish for their screenshots to be widely shared by people, then he or she must post them in a private album and place a watermark or some other form of identification on the images.
And btw, weren't those screenshots taken to be shared by other players? They were. They must be everywhere on the internet by now.
So why is the person complaining at all? What is it that she wants?
Let me try this once, and then we can agree to disagree if that's the case.
She makes edits to those screenshots--lighting, color, shading etc. Since she has edited them, it is not just a BASIC screenshot/screengrab that anybody could post on the internet. She did work on them. So, for someone else to post them without crediting her, is basically that person saying, ">>I<< did the work on these screenshots." >>They<< are essentially assuming credit for the modifications >>she<< made. Which is kinda really not cool of them.
As for intellectual property--of course the LEGAL rights belong to Bioware/EA. We're talking courtesy and appreciation of the work she put in, here, not legalities.
I write fanfiction. If I write a story about DA characters, and someone copies and pastes that story into their journal etc. without crediting me, they are assuming credit for my work. That's still plagiarism, albeit the kind you can't sue over since the characters are not mine. But yes, still plagiarism. The same applies to fan art work of any kind.
