Don't be afraid of stock images!
Consider using stock images. Stock images are not for every post. While they don't work for a post about a craft or a handmade product or recipe, they are ideal for many other situations. For example, if you write about parenting advice, your pictures don't have to be of your kids. If you're writing a post about how to chose the best dog food for a specific breed of dog, the image in your post does not have to be of your dog. If you write about business advice, you don't have to stage a picture in an office setting. Those are ideal situations for stock photography.
For example, I wrote a post about helping kids declutter. I staged a crazy picture in my backyard that involved a ladder and dumping the contents of my daughter's junk drawer in her lap. The photo did okay on Pinterest, but not great. Why? My picture is not very attractive. I'm obviously not a photographer.
On the other hand, this stock photo that I used for a post about getting organized did fantastic on Pinterest. Why? It's a clean, beautiful image with a clear title.
Stock images can get expensive, but sites like Pixabay and Picxclicx offer free stock photos. I have a subscription with Graphic Stock for $100/year for unlimited photos. Of course it will depend on your business size which option will be best for you. If you'd like to give Graphic Stock a try, please use my referral code.
