Can a whole brokerage use my pictures?

I have been booked recently by a broker for a few properties. After I deliver the pictures, I see that all the realtors that work for the brokerage post the same pictures as their newest listing. I have also shot for another realtor and deliver the pictures as usual. Then, a few days later, other realtors post a graphic with the pictures that the other agent hired me to take. Should I be compensated for this or no LOL
