I am fortunate to get hired four or five times monthly by realtors to take photos of luxury homes along the north shore of Chicago. Realtors frequently post these photos to MLS and their Instagram accounts and credit my Instagram username for the photos. To increase my Instagram following in an effort to attract more business, I want to post photos on my Instagram account to show other realtors the quality of my photos. Law is about intent. My intention is simply to show my skills and attract realtors to hire me? I Assume I do not disclose property address and there are no people in the photos. Do I need to get permission from the realtor or homeowners to post such photos?
