 * Hello,
 * I recently started my site using theme sela. I did quite some changes to the 
   CSS including removing the RHP from the post pages.
 * It works absolutely fine although the images that I upload now to fit in that
   wider space (1070 x 408px) are not as sharp as they should be.
 * After some research, I realised that it’s because it still has as a default the
   original size of 820px wide, so it just reduces the featured image at some point,
   and expands them to the space it has, making them less sharp.
 * Where and how can I fix this? I have had a look at the CSS, php and more but 
   no luck.
    Here’s a link: [http://worklifeworld.com/you-only-had-one-job](http://worklifeworld.com/you-only-had-one-job)
 * They show as /wp-content/uploads/2016/06/finihsmed-820×312.jpg whilst the original
   file is 1070×408 (/wp-content/uploads/2016/06/finihsmed.jpg), and in the source
   I see those smaller dimensions too when inspecting the element but I can’t findwhat
   it refers to in the backend.
 * Thank you for the help!

 * Hi [@worklifeworld](https://wordpress.org/support/users/worklifeworld/),
 * Sela is programmed to crop thumbnails at 820px by 312px. This is set in the **
   sela_setup()** function in the theme’s **functions.php** file:
 * `set_post_thumbnail_size( 820, 312, true );`
 * You can override the parent theme’s function by first [creating a child theme](https://codex.wordpress.org/Child_Themes)
   and then adding the following to the **functions.php** file in your child theme:
 *     ```
       function sela_child_thumbnail() {
           set_post_thumbnail_size( '1326', '995' );
       }
       add_action( 'after_setup_theme', 'sela_child_thumbnail', 11 );
       ```
   
 * You may need to regenerate your thumbnails before noticing a change. The following
   plugin will handle that on your behalf:
 * [https://wordpress.org/plugins/regenerate-thumbnails/](https://wordpress.org/plugins/regenerate-thumbnails/)
 * Let me know how you get on with those steps or if you have any extra questions
   while walking through them.

 * Worked like a charm, thank you so much!
 * Now I have sharp thumbnails, only need to resize a handful of them that I never
   cropped 🙂
 * Thank you!!
