Look at the background and the other people
Open the image full size. Crop out a badge, a car registration or a letter on the table. Choose a different photo if a friend or partner would prefer to keep the occasion private. A portrait you already use for work may make it easier to connect the two profiles.
Ask what private means to both of you
Before sending a personal photo, ask whether the recipient wants it and who can see their messages. If you are chatting with a couple, clarify whether both partners read the account. A useful question is “Is this just for you, or would you like to show your partner?” A recipient can save a copy even if you later remove the original.
Make a plan that keeps your address private
For a first meeting, suggest a public place that each person can reach independently. Agree on a meeting point near the entrance instead of exchanging home addresses for a lift. You can always share more after you have met and decided you want another date.
