Drupal - Preview image after uploading using Form API

Define the theme in the field, and simulate the code structure to preview the image that you just upload. My solution is as follows,

$form['abc_field']['abc_filename'] = array(
        '#type' => 'managed_file',
        '#title' => t('abc image'),
        '#upload_validators' => array(
            'file_validate_extensions' => array('gif png jpg jpeg'),
            'file_validate_size' => array(1 * 1024 * 1024),
        ),
        '#theme' => 'abc_thumb_upload',
        '#upload_location' => 'public://abc/'
    );

In your hook_theme(),

return array(
    'abc_thumb_upload' => array(
        'render element' => 'element',
        'file'           => 'abc.module',
));

In your theme_abc_thumb_upload(),

function theme_abc_thumb_upload($variables) {

    $element = $variables['element'];

    if (isset($element['#file']->uri)) {
        $output = '<div id="edit-logo-ajax-wrapper"><div class="form-item form-type-managed-file form-item-logo"><span class="file">';
        $output .= '<img height="50px" src="' . file_create_url($element['#file']->uri) . '" />';
        $output .= '</span><input type="submit" id="edit-' . $element['#name'] . '-remove-button" name="' . $element['#name'] . '_remove_button" value="Remove" class="form-submit ajax-processed">';
        $output .= '<input type="hidden" name="' . $element['#name'] . '[fid]" value="' . $element['#file']->fid . '">';

        return $output;
    }
}

about dimension check this validation file_validate_image_resolution:

$form['logo'] = array(
      '#title' => t('Logo'),
      '#type' => 'managed_file',
      '#required' => TRUE,
      '#default_value' => variable_get('logo', ''),
      '#upload_location' => 'public://',
      '#upload_validators' => array(
            'file_validate_extensions' => array('gif png jpg jpeg'),
            'file_validate_size' => array(0.3*1024*1024),
            'file_validate_image_resolution'=>array('100x100'),
  )

I have resolved the issue with a simple fix. You can add a theme to the form element "tbs_thumb_upload" and in the theme file hand the element as mentioned in the theme file code.

 // THIS IS THE FILE FIELD  
 $form['logo'] = array(
  '#type' => 'managed_file',
  '#title' => t('Logo'),
  '#description' => t('Allowed extensions: gif png jpg jpeg'),
  '#upload_validators' => array(
    'file_validate_extensions' => array('gif png jpg jpeg'),
    // Pass the maximum file size in bytes
    'file_validate_size' => array(1 * 1024 * 1024),
  ),
  '#theme' => 'tbs_thumb_upload',
  '#upload_location' => 'public://society/',
  '#attributes' => array('default_image_path' => TBS_IMAGE_DEFAULT_SOCIETY)
  );

 // THIS IS THE THEME FILE : THEME : tbs_thumb_upload : Theme file code
 if (!empty($form['#file'])) {
   $uri = $form['#file']->uri;
   $desc = FALSE;
 }else {
   $uri = $form['#attributes']['default_image_path'];
   $desc = TRUE;
 }

 // Render form element
 print drupal_render_children($form);
