Doesn't Support Removal of Images in an Image Field

Could you screenshot the before / after behavior please, i'm not sure to get where megarow is involved?

Sorry, nigelwaters and I were working on this issue together. We should have posted more info.

Here are some screenshots to demo what I am talking about:

The issue that you are having is that the form rendered is defined in an external file (eg: the node_form is defined in the file node.pages.inc)

To fix that you need to describe to the system where the form should be included from. In your case i think that you were editing a product display which is a node that you are editing, including the form file such as below should fix it:

/**
 * Implements hook_form_alter().
 */
function views_megarow_form_alter(&$form, &$form_state, $form_id) {
  if (strpos($form_id, '_node_form') !== FALSE) {
    form_load_include($form_state, 'inc', 'node', 'node.pages');
  }
}
