Allow users to upload account photo in "Sign up form"?

I have a sign up form ,which contains required fields to create account (Last name ,First name,User role,Email ,password ) ,but I added other stuff that allows user to upload photo for his account ,I found that most of application make this in second step or after open dashbaord.

This is my Sign up form ,when the user click on account-photo-image-view , a file chooser will opened.I have these questions :

1-Should I remove this process from the sign up form and add it in dashboard ?

2-If I can save it like this ,should I add a Button to upload Image ?
