Responsive image in a field collection

Hi,

I'm currently using drupal plugins to make a content type image field as responsive. It works ok.
When rendering, the expected java code is generated. When it is a first level field is works fine:

print render($content['field_imagen']);

I'm also using the field collections module in order to create repetitive field blocks inside a content type. I can access all this information. Both modules work ok.

My problem arises when trying to generate a responsive image inside a field collection. I have no way to render the image.

To go through the filed collection I'm using the following code but in the last field (responsive image) I only get information about the initial image but it doesn't render:

// Get the field collection items. $fc_fields = field_get_items('node', $node, 'field_columna'); // Extract the field collection item ids $ids = array(); foreach ($fc_fields as $fc_field) { $ids[] = $fc_field['value']; } // Load up the field collection items $items = field_collection_item_load_multiple($ids); // Loop through the items and extract field values foreach ($items as $item) { $site_name_fields = field_get_items('field_collection_item', $item, 'field_texto'); $site_name = array_shift($site_name_fields); $name = $site_name['value']; print render($name); $site_name_fields = field_get_items('field_collection_item', $item, 'field_imagen_fija'); $site_name = array_shift($site_name_fields); $name = $site_name['filename']; $uri = 'public://'; $path= file_create_url($uri).$name; echo '<img src="'.$path.'">'; $site_name_fields = field_get_items('field_collection_item', $item, 'field_imagen_col'); $site_name = array_shift($site_name_fields); $name = $site_name['filename']; print render($name); }

Plugin and images information are in the database because the next code generates responsive images rendering but for all the collection though I want to render only the image:

$rendered = drupal_render(field_view_field('node', $node, 'field_columna'));
print render($rendered);

Any help will be very appreciated.

Thank you.
