Why would you want to share your photos in so many places? Doesn't that just open your work up to be stolen or copied? Yes, yes it does. However, if you've watermarked or branded your images in a way that will lead people back to your website, this also means that you're essentially advertising your work to many different people all at once! It's free, it's easy, and now there's a way to make it more efficient!! I'm happy to let potential wedding planners and clients borrow my branded images for their blog or wedding idea page! The more the merrier!
