Instead of this message in item.php: "Seller has not uploaded any pictures", how can I make it show a photo as background?

This photo I uploaded I want to put

you need to edit item.php and instead of that message, but there <img src="..."/> tag

I have put this code " <div class="home-empty">
                  <img src="<?php echo osc_current_web_theme_url('images/no-image-found-360x250.png'); ?>" /></div>
              <div class="image-empty"><?php _e('Seller has not uploaded any pictures', 'beta'); ?></div> " and both the message and the image work. So when there is no picture of the user, when a share is made on Facebook it pulls the picture I put. It's correct?

Facebook should us OG tags (Structured data), but may get one from page as well.
