Intro image - intro text

Why not working this code:
<div class="row-fluid">
<?php if (isset($images->image_intro) && !empty($images->image_intro)): ?>
<?php $imgfloat = (empty($images->float_intro)) ? $params->get('float_intro') : $images->float_intro; ?>
<div class="img-intro-<?php echo htmlspecialchars($imgfloat); ?> col-lg-4 col-lg-reset col-md-4 col-md-reset col-sm-4 col-sm-reset col-xs-12 col-xs-reset">
<img
<?php if ($images->image_intro_caption):
echo 'class="caption"'.' title="' . htmlspecialchars($images->image_intro_caption) . '"';
endif; ?>
src="<?php echo htmlspecialchars($images->image_intro); ?>" alt="<?php echo htmlspecialchars($images->image_intro_alt); ?>"/>
</div>
<?php endif; ?>


<?php if (isset($images->image_intro) && !empty($images->image_intro)) { ?>
<div class="col-lg-8 col-lg-reset col-md-8 col-md-reset col-sm-8 col-sm-reset col-xs-12 col-xs-reset">
<?php } ELSE { ?>
<div class="col-lg-12 col-lg-reset col-md-12 col-md-reset col-sm-12 col-sm-reset col-xs-12 col-xs-reset">
<?php }?>
<?php echo $this->item->introtext; ?>

When I edit the article, I put the picture as intro and full image in 'images and links' tab. This picture should appear in the bolded (accentuated) line of the code part I've inserted above. But it isn't there, it is placed simply to the intro text. Could you tell me why this happens?
