Improving post thumbnail quality?

Hi VierasTalo,

The resolution of the thumbnail image quality on the page your link points to can come from changing one of the 2 options outlined below:

1) functions.php:

Open functions.php and find this line towards the top of the page:

function alx_setup()

In this function you find this piece of code:

// Thumbnail sizes
add_image_size( 'thumb-small', 160, 160, true );
add_image_size( 'thumb-standard', 320, 320, true );
add_image_size( 'thumb-medium', 520, 245, true );
add_image_size( 'thumb-large', 720, 340, true );

The size used in that page is thumb-standard. If you change the size there, you should be able to have a better quality.

2) Alternatively, open this template file: content-standard.php in a code editor. Find this line of code towards the top:

<?php the_post_thumbnail('thumb-standard'); ?>

If you replace thumb-standard with a higher-resolution thumbnail size, like thumb-large, should result in a better looking image.

However, because you’ll be changing the theme files, my recommendation is to create a child theme, so your mods will survive a theme update. If you need help creating a child theme, this plugin could help:

I hope this answers your question, if you need help with anything outlined here, please keep posting here.

Cheers!

Thank you! The functions didn’t include thumb-standard, but the content-standard was actually using thumb-medium so I edited the size of that one and it worked well. Now I just need to get a plugin to re-do all our thumbnails… Oh well. Thank you for the help, I really do appreciate it!

I’m glad you solved the problem. Have a great weekend!
