I'm working with Radio Helper with 'parse'=>'image' option in a widget .
look at this please:
$form->add(new \IPS\Helpers\Form\Radio("var_name", isset($widgetConfig['var_name']) ? $widgetConfig['var_name'] : 'val1', FALSE, array(
'parse' => 'image',
'options' => [
'val1' => \IPS\Theme::i()->resource('display/filename.jpg', 'myapp', 'admin'),
'val2' => \IPS\Theme::i()->resource('display/filename2.jpg', 'myapp', 'admin')
]
, 'descriptions' => [
'val1' => 'Description',
'val2' => 'Description'
]
)));
in the development mode, the code works and shows images with radio button but in the production mode doesn't work .
