Use image from taxonomy term as exposed filter option
Use "Better exposed Filters" and choose its Display setting as Checkbox
Now you have to do form alter like this

function THEMENAME_form_views_exposed_form_alter(&amp;$form, &amp;$form_state) {
  foreach ($form['TAXONOMY_ELEMENT']['#options'] as $tid =&gt; &amp;$name) {
      $term = taxonomy_term_load($tid);
      $name = '&lt;img src="' . file_create_url($term-&gt;IMAGE_FIELD_NAME['und'][0]['uri']) . '" /&gt;';
  }
}


In my case :: 
TAXONOMY_ELEMENT = field_type_tid
IMAGE_FIELD_NAME = field_term_image
