 * Hi,
 * I’m displaying posts on the home page and question is how do I show the featured
   image as a thumbnail for each post. I’m completely new so if you could let me
   know which php file I would need to edit to show this would be great.
 * Thanks,
 * Huzza

 * Hi, first of all don’t edit any core files (no theme core files, no plugin core
   files and no wp core files)!
    What you first have to do is to create a child 
   theme (you can read the codex here: [http://codex.wordpress.org/Child_Themes](http://codex.wordpress.org/Child_Themes)
   Or use a plugin to create a child theme like: [https://wordpress.org/plugins/one-click-child-theme/](https://wordpress.org/plugins/one-click-child-theme/)–
   activate the child theme after that see what page is set for homepage in your
   dashboard, then in the right of that page you’ll see what template it uses, copy
   that file from the theme to the child theme – now you can edit it in the child
   theme. In that file see where the featured image is output and change the code
   you have with one of the functions you have described here: [http://codex.wordpress.org/Post_Thumbnails](http://codex.wordpress.org/Post_Thumbnails)
   Please check the codex to see which one you want to use.

 * Some basic instructions on creating a child theme:
 * 1) Open an FTP program and go to the wp-content/themes directory in your server
   for the domain you are trying to do this on.
    2) Notice the theme directory of
   the theme you are using. Example: twentyfourteen 3) Create a new directory in
   the themes directory and name it the same as your themes name with -child appended
   to it. Example: twentyfourteen-child 4) Copy as a BARE minimum the style.css 
   file from your current theme into the new directory and open it. Add in this 
   line (using our current example of twentyfourteen): Template: twentyfourteen 
   5) Also consider appending to the line that says: Theme Name: the word child:
   Theme Name: Twentyfourteen Child 6) Copy any files you wish to edit into the 
   new theme’s directory. Edit them in there and don’t touch the files in the old
   directory. This way when a new version of that theme gets published and you update
   it in your blog the files you have changed don’t get overwritten.
 * Now go to your wordpress blogs admin and switch to this new child theme.
 * * Do not copy the functions.php file into the new child theme directory. This
   is break your blog. If you intend to add functions code just create a new file
   inside the child theme called functions.php and only place into it the new code
   which will be run along with the old functions.php file’s code.
