User profile pictures

3 Questions:

1a) Using JQuery. a user creates 2 profiles and wants to add a profile picture, I installed the Picture upload plugin and can upload the pictures to the database but when i go to call up the picture the same picture shows for the 2 different profiles. How can i trace which profile is being edited and so that picture only shows up on that profile?

1b) Using the above plugin i only get the option to take a picture, is there a way i can select from files?

2) My app behaves differently depending on whether I test it using the appery tester app or the online test page. Why does this happen as if I have an error I do not know which one to fault find. A lot of the time i need to refresh or restart the test (a couple of times) to see my changes. Are there any known issues?
