 * Hello,
    First of all, please excuse me for my bad English, this is not my natural
   language. I’m here because I don’t know WordPress well, then need your help to
   fix a little problem that I can’t find out how to fix by my own.
 * <b>What I want :</b>
    I want my pages to display thumbnail pictures. I want those
   pictures to have a size of 940*200 when displaying the page on a computer screen,
   and a smaller size (responsivity, that kind of stuff) on phones. I also want 
   those pictures to have a size of 300*175 when I display a list of the pages (
   thumbnail+title).
 * <b>What I did :</b>
    I first went in “settings>medias” to change the sizes. But
   whatever the size I put in there, it doesn’t change anything of the thumbnails
   that are displayed on my pages. As I had no idea why it doesn’t work and what
   I’m supposed to do, I went to Google to find another way. I found some PHP codes.
   I added this one to functions.php:
 *     ```
       add_theme_support( 'post-thumbnails' );
       set_post_thumbnail_size( 200, 300, true ); // Miniatures de l'accueil
       add_image_size( 'miniature-archives', 200, 9999 ); // Miniatures des archives
       ```
   
 * and added this to page.php
 *     ```
       <?php if ( has_post_thumbnail() ) { // dans la boucle
       the_post_thumbnail();
       }?>
       ```
   
 * It doesn’t work neither. I asked someone that told me to use the “Post Thumbnail
   Editor” plugin. But… neither.
 * <b>The problem :</b>
    Whatever the size I set, whatever the feature I use, here
   is what my thumbnail look like: [http://www.iut-lens.univ-artois.fr/wordpress/wp-content/uploads/2014/05/MMI-10×150.jpg?7499c](http://www.iut-lens.univ-artois.fr/wordpress/wp-content/uploads/2014/05/MMI-10×150.jpg?7499c)
   The thumbnail’s adress indeed says it’s a 10×150. But according to “Post Thumbnail
   Editor”, it’s supposed to be 200*300
 * Why do I have this 10×150 size? How can I do to change its size?
 * Thanks for your help….

 * Hello
    Thanks a lot for your answer, but I finally found some support elsewhere
   and achieved to fix the problem…. I’m sorry for the bother.
