I haven't found a way to set your main profile photo on meetup.com such that it overrides any old photos you have set in individual groups. This script will do just that — set your group specific profile photo to your main photo for every group you're in.
Here's what to do:
- Go to your main profile page: http://www.meetup.com/profile/
- Ensure you've set your main profile photo to the photo you want to use in all your groups.
- Open your browser's developer tools (often F12 on Windows, cmd+opt+i on macOS), copy the following code, paste it in the Console tab, and press
var memberId = 56746842; // <=== Edit this
