WordPress does do some compression on images when it resizes them. You can disable this very simply using the following code (or using a plugin like this one): function wpse_114909_image_quality() { return 100; } add_filter( ‘jpeg_quality’, ‘wpse_114909_image_quality’ ); I’m sure that GD & Imagemagick are not as good at resampling images as Photoshop is, so … Read more
A screenshot explain better than words:
This kind of works but it is outputting 1 post title in particular and for all the images on the page. Any thoughts as to why its not dynamically picking up each images associated post title? $attachments = get_posts( $args ); foreach ( $attachments as $image ) { // Get the parent post ID $parent_id … Read more
Download the script (or add it via npm > bower to your theme), wp_enqueue_script() it at the wp_enqueue_scripts hook and then simply add/enqueue another (your custom) script where you add the contents of the demo index.html file: ( function( $ ) { $( “img” ).photoResize( { bottomSpacing: 15 } ); } )( jQuery || {} … Read more

I was having trouble with this too. Wanted to show all the term images on a single post page. I found that you need to loop through the terms first (in my case, taxonomy=st_colors), then loop through the images associated with those terms. Here is how I solved it: <?php $terms = get_the_terms( $post->ID, ‘st_colors’ … Read more
I believe you need to pass the third $crop parameter to set_post_thumbnail_size. In other words… set_post_thumbnail_size(80, 80, true); That third parameter enables a “hard-crop” mode. From the Codex: Set the default Post Thumbnail size by cropping the image (either from the sides, or from the top and bottom): Without that argument, or with it set … Read more
