I can't figure out how to make a search button on the view's exposed (as a block) search filter to be styled similarly as in Drupal standard search form, with a 'lens' icon. The examples for hook_form_alter() I found using:
$form['submit']['#type'] = 'image_button'; $form['submit']['#src'] = base_path() . path_to_theme() . '/images/search-button.png';
-don't seem to work correctly, as image on the button just doubles (png file includes both 'active' and 'inactive' images of lens). Could there be a straightforward way for the search button 'lens' styling, not including CSS/templates modifications?
