Hey, my name is Fedor. I operate YTGraphics.com. It was originally founded in April 2013, I bought it 5 months later and developed it into what it is today.
Right not there are hundreds of YouTube banners available for free to download, mostly gaming related, although I'm starting to branch out. My goal is for YTGraphics to be the #1 source for all YouTube graphic needs.
All images that are available for download on this site are free to use for anyone. I don't require acknowledgments or credit, but a link bank to the website from your profile description is always appreciated.
