Cannot output image using render()

Question

I am trying to output this image :

However, nothing gets printed out. My code is

print render($media_item->field_media_photo['und'][0]

Why doesn't it work?

Answer 1

Use image_style_url instead.

$image_uri = $media_item->field_media_photo['und'][0]['uri'];
$image_stylePath = image_style_url("large", $image_uri);
print theme("image", array(
    'path' => $image_stylePath
));
