Improve listing CSS to handle thumbnails of any size.

These style changes don't work when alt and/or title texts are allowed to be defined by the editor.

So, I think it is not such bad idea to use thumbnails of known predefined dimensions. However this module should define its own image style for that and not "hijack" the Drupal defined thumbnail image style. An example of a module doing so is Linkit (7.x-2.x version), but basically it comes down to defining the hook like below (copied from a features generated module). I found this issue because I had a problem with this module, because my thumbnail dimensions have been overruled for other purposes...

function plup_image_default_styles() {
  $styles = array();

  // Exported image style: plup_thumb
  $styles['plup_thumb'] = array(
    'name' => 'plup_thumb',
    'effects' => array(
      4 => array(
        'label' => 'Scale',
        'help' => 'Scaling will maintain the aspect-ratio of the original image. If only a single dimension is specified, the other dimension will be calculated.',
        'effect callback' => 'image_scale_effect',
        'dimensions callback' => 'image_scale_dimensions',
        'form callback' => 'image_scale_form',
        'summary theme' => 'image_scale_summary',
        'module' => 'image',
        'name' => 'image_scale',
        'data' => array(
          'width' => '100',
          'height' => '100',
          'upscale' => 1,
        ),
        'weight' => '0',
      ),
    ),
  );

  return $styles;
}

Can anyone provide .zip with working patch for various thumbs sizes? I dont have shell access.

Added description to images.
