Thumbnail sizes

@jerryb2013 Do you have that image size available?

Also, did you update the CSS used?

well, I had changed the thumb size to 200 x 200 in settings, and update css and media queries … should I try it a different way?

Does your theme have a 200×200 image size set?
If not it needs one.

also tried adding custom size, add_theme_support( ‘post-thumbnails’ );
add_image_size( ‘blog-thumb’, 200, 200 ));

but still got 150/200 rendered

Did you change the thumbnail and then regenerate thumbnails using the plugin above?

the_post_thumbnail( 'blog-thumb' );

yes, that’s right; it changes the height, but not the width
<img width="150" height="200" src="https://localhost:10058/wp-content/uploads/2022/07/043-Cindy-Wigfield-1152x1536-1.jpg" class="attachment-blog-thumb size-blog-thumb wp-post-image" alt="" loading="lazy" srcset="https://localhost:10058/wp-content/uploads/2022/07/043-Cindy-Wigfield-1152x1536-1.jpg 1152w, https://localhost:10058/wp-content/uploads/2022/07/043-Cindy-Wigfield-1152x1536-1-225x300.jpg 225w, https://localhost:10058/wp-content/uploads/2022/07/043-Cindy-Wigfield-1152x1536-1-768x1024.jpg 768w" sizes="(max-width: 150px) 100vw, 150px">

Just tried again, and it worked this time … not sure which step I messed up, but after clearing cache, thumbs are now 200 x 200
thanks

Nice! Glad you solved this one.
