Hi Louise,

The way it currently work is that the first picture uploaded into a category (before, current, or after) is that it picks up the first one uploaded.

So once you have one already there, follow-on updates will not change it in your profile.

To change the one currently in your profile, click "Edit photo" on the picture you want to replace. In the edit options, upload the other picture, and it should replace it.

If this doesn't work, just let me know.

Wa'il
