I can't seem to print render an image on my page.tpl.php.
This is the code I use:
<?php print render($content['field_image']); ?>
I can get the title to show up though: <?php print $title; ?>
So what am I doing wrong?
Because you're in a page.tpl not a node.tpl, field_image isn't in $content. The only thing in $content should be regions, which contain blocks.
Use this instead: https://www.drupal.org/project/fieldblock
Here you can use fields as a block. Very easy :)
