seems to log activity only for photos directly postet in the profil.
Correct, it directly states that is the case in the system actions description.
how can i manage to log activity fpr photos in galleries too?
You can't, the activity parsing isn't able to handle random galleries it can't possibly know about so all the access checks will fail. You can make a copy of the system action and remove the asset condition, but it probably won't work.
