Here's one pic I found right off the bat just putting in 'cosplay' at Google News.
I'd try typing in '(Friday) Cosplay of NYCC 2013' into Google. Thats how I found most of my pictures. Or I've found a few on Tumblr too.
I also emailed Wikia to see if they had any video footage from the contest Friday, which they still have yet to get back to me about. But I'm patient. Took a few months until I found a few videos from the cosplay contest from NYCC 2012 so who knows when this year's videos will start pouring in.
It was really nice meeting and talking with you before the Wikia Contest
Really hope to see you at the next NYCC!
