?>" />

                        'mode'     => false,
                        // Can be set to false to allow any media type, or can also be set to any mime type.
                        'desc'     => __( 'Basic media uploader with disabled URL input field.', 'redux-framework-demo' ),
                        'subtitle' => __( 'Upload any media using the WordPress native uploader', 'redux-framework-demo' ),

                            'content' => 'This is a <b>hint</b> tool-tip for the webFonts field.<br/><br/>Add any HTML based text you like here.',
                        )
                    ),

Hey if you want to hide WordPress title and description after upload logo then change your code to like this

     <?php global $redux_demo; ?>
        <?php if ($redux_demo['opt-media']['url'] != ' ') { ?>
             <img src="<?php  echo '' . $redux_demo['opt-media']['url']; ?>" />

         <?php } else { ?>
             <span class="site-title">
               <a href="<?php bloginfo('url'); ?>" title="<?php bloginfo('name'); ?>"><?php bloginfo('name'); ?></a>
           </span>
              <h4 class="site-desc"><?php bloginfo('description'); ?></h4> 
     <?php } ?>

I think it will work fine
