Hi guys,

I m newbie in WordPress. I wanted custom fields during user registration and for that i have used cimy extra field plugin. Now i want to edit user field from front end. I m successfully updating users extra text fields but i m unable to update users picture field(basically change profile custom picture)

Following is my form which i m using in front end

<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>
