$repeater_fields[] = $options_panel->addImage( 'image_field_id',
    array(
        'name'=> 'My Image ',
        'desc'=> '',
    ),
    true

    array(
        'name'=> 'My Image ',
        'desc'=> '',
    ),
    true

/* Then just add the fields to the repeater block */
$options_panel->addRepeaterBlock( 're_',
