Edit User Profile From Front End

I have taken reference from this link. I have used Plugin
cimy user extra fields
for extra users’ field. I have taken few extra fields such as picture upload and file upload.

Now I want to edit user profile from front end. I am able to edit user text fields(both extra and normal fields), but I am not able to change their picture or file.

I have also tried to use few plugins such as profile builder, wp user frontend but have not been successful in doing so. Below is my code which i have used for editing user profile from front

Form

 <form method="post" id="your-profile" action="<?php the_permalink(); ?>"  enctype="multipart/form-data">
                                <table>
                                    <tr>
                                        <td><label for="first-name"><?php _e('First Name', 'profile'); ?></label></td>
                                        <td><input class="text-input" name="first-name" type="text" id="first-name" value="<?php the_author_meta('first_name', $current_user->ID); ?>" /></td>
                                    </tr>
                                    <tr>
