Image featured post problem multi language

Hi there,

I am having an issue with multi language when displaying the thumbnail picture.

<?php if (has_post_thumbnail()) : ?>
                        <div class="preloader GMnewslist"><a href="<?php the_permalink() ?>" class="bwWrapper link-icon"><img src="<?php echo TMM_Helper::get_post_featured_image($post->ID, '100*100'); ?>" alt="<?php the_title(); ?>" /></a></div>
                    <?php endif; ?>

And here’s the EN version:
EN

And here’s the PT and ES version:
PT & ES

Any ideas why this is happening?
