When you want to delete a photo from your user or organisation profile or your project page, you will first need to select a new one.
Log onto betterplace.org, click on “My betterplace” and go to the desired profile or project page. From your user profile, click on “manage photos”, from your organisation page go to “upload logo”, and from the administration area on your project page select “Manage photos”. In any case, upload a new photo and then scroll over it and mark “Use this picture as profile picture”. Then you take the old photo and remove it with a click on the red X. This applies to your project page for both your main profile photo and your secondary smaller one.
