Help Me Find Users and Photos of Home Decor I Can Use for my Website

I am launching a new website which involves users uploading photos of their home (Various rooms such as home office, basement, home theater, garage etc...). I need help in either finding content that I am able to use without any legal restriction and/or users who are willing to try my website out and upload their own content. I could also use help in finding galleries or albums of photos and consent from the owner to use them for my website. Let's chat and discuss.
