How to politely reject a girl after she sends full body pics?

From Coffee Meets Bagel, I set up date but didn't see full body pic so I requested it. The pics don't look good so I don't want to go on the date anymore. After sending the full body pic, she asked me if I still wanted to go on the date. How do I reply that I'm not interested without making her hate me and report me on the dating app?
