How to remove photos from profile that are from client and sitter text exchange?

Hello! I find that my profile contains all photos from the text/app exchange with my clients. Sometimes I need to send them photos that are not necessarily of their dog (for example: sending a screen grab of a profile for a fellow dog that is coming on the same day.) How can I remove these unwanted pics? (I already went to the edit mode under my profile's photo section, and it only shows photos I've uploaded,not the ones from client exchange.)

Thanks in advance for any help! -Leah
