I don’t think it works that way. I think remove_image_size only affects image sizes created by plugins or themes, not the core ones in WordPress (could be wrong). If you want to use it to remove “custom” sizes you added, you will still need to hook it into an action to actually run it: function … Read more

If you really need to keep the size of your images, but want to keep your file sizes down, consider processing your images first with tinypng.com. Their online … Read more
the_post_thumbnail() and get_the_post_thumbnail() will output the complete HTML for displaying that image. So this <img class=”img-responsive” src=”https://wordpress.stackexchange.com/questions/274181/<?php the_post_thumbnail(); ?>” alt=””> will be rendered to something like this <img class=”img-responsive” src=”https://wordpress.stackexchange.com/questions/274181/<img src=”…” alt=”..” class=”..”>” alt=””> which is not valid HTML and you can’t really tell how browsers will display this. Now you have 2 choices: Use … Read more
You should not attempt to know the user device on server side, as this kind of thing will mean you will not be able to use any page caching, and it will fail when the browser “window” size changes. Do such decisions on client side. If it is impossible to simply use CSS, just prepare … Read more

You can manipulate the main WP_Query just before it asks the database for posts. Looking for an existing _thumbnail_id meta field should suffice, so using the pre_get_posts filter, something like this might work for you: add_action(“pre_get_posts”, function($query) { if(!is_front_page() || !$query->is_main_query()) { return; } if(!array_key_exists(“meta_query”, $query->query_vars)) { $query->query_vars[“meta_query”] = array(); } array_push($query->query_vars[“meta_query”], array( ‘key’ => … Read more
Change image size medium to large e.g the_post_thumbnail( ‘large’ ). If you enlarge 300px image to 600px your image will be distorted. Or if you need more control on image size then you have to register a new image size using add_image_size().
Try using get_the_title instead of the_title – from the Function Reference: the_title – Display or retrieve the current post title with optional markup. get_the_title – Retrieve post title. You might notice that the_title says “Display or retrieve” – and it’s true, you can pass false to the third parameter of the_title to get it’s output … Read more
Like this: ‘alt’ => get_the_title(). ‘ review’ So the full code would be: <?php the_post_thumbnail(‘250px’, array(‘class’=>”review-siteshot”, ‘alt’ => get_the_title(). ‘ review’ )); ?>
The third parameter you can pass to get_the_post_thumbnail is $attributes, which you can use to pass custom HTML attributes including classes. $thumbnail = get_the_post_thumbnail( get_the_ID(), // Post ID. ‘thumbnail’, // Image size. array( // Attributes ‘class’ => ‘my-custom class-names’, // Classes go here. ) ); Note that this will override the default image classes that … Read more
