Why are my featured images blurry?

    I’ve tried several themes with featured images and the images are all blurry on the front page. I’ve even changed the CSS so the images are larger and in the same ratio as my original photo.

    When I click on the actual post, the full size image comes up and there is not an issues unless it wasn’t high quality to begin with.

    I never used to have this happen with themes. I’ve used featured images for many years with no issues. It has only started happening in the last six months and seems to happen with every theme I try. Any thoughts?

  • All your thumbnails on homepage are of 150x100px resolution.
    So i guess your homepage is taking the default value of thumbnails for images and displaying.

    Check for the following in your functions.php file in your theme folder:

    add_theme_support( 'post-thumbnails' );
add_image_size( 'thumbnail', 150, 100, true );

    ^ this checks if your theme supports thumbnails. And the second line specifys the image dimensions of thumbnail.
    If these exists, they will override WordPress default settings!

    Since you checked with multiple themes, i guess we will look into WP settings next:-
    Go to your Dashboard -> Settings -> Media.. Change the thumbnail size to a higher resolution, say 450×300.
    Save Settings and check with next post.

    Note: These settings will be applicable to all new posts which you further publish, old posts WILL NOT get effected!
    I guess there are some plugins which may help you with regenerating thumbnails with new dimensions for old posts. Am unsure. Check.

    Regeneration plugin does not help, changing the sizes doesn’t work for all, it didn’t for me. My photos are 1024 so I don’t understand why at any smaller preset in the settings, it would cause the photo to be blurry. This just started like last week or so.
