field - Drupal 7 alter node display -

i have content type 2 image fields, banner , logo.

i trying implement logic allow 1 of 2 display depending on whether editor elected display banner or logo radio button options.

i setup little custom module implementing hook_node_view , tried unset image field node object no joy. code fragment below:

function mymodule_node_view($node, $view_mode, $langcode){ unset($node->field_main_picture[$node->language][0]); unset($node->field_main_picture); $node->field_main_picture = null; }

none of attempts worked.

any suggestions, please?

i found reply question.

the node object contains array called content renderable info drupal print screen. it's in array unsets need take place. i.e:

unset($node->content['field_main_picture']);

and main image image disappears.
