I currently have an interface for editing a user's profile in a web app:
There's a discrete form in each tab of the accordion with its own submit button.
Now the question: I have seen sites such as facebook immediately upload and use a picture once the user has selected it from the browser's file selection diaglogue, hence, there is no need to submit the form after selecting the file.
However, in my case, I have a submit button for updating those text fields. Should I immediately upload and save the picture and update the displayed picture (and immediately delete the picture if the "x" is clicked) without the user having to click the "update profile button"? For updating the text fields, they would need to click the "update profile" button for the changes to be saved.
Is this something that can confuse users?
