I want to change the order of fields in login/registration form I've user login/registration form in my drupal 7 site. Two links in this form: "Create new account" and "Request new password" are appearing before captcha. And I'm trying to place these links after captcha and before button. How can I achieve this?:
You probably should hide this fields, and show them with javascript before captcha input value is not empty. Check it with "on change" function: 

 $('body').on('change', '#CAPTCHA INPUT', function(){}
