This function will generate an image by temporarily registering an image size, generating the image (if necessary) and the removing the size so new images will not be created in that size. function lazy_image_size($image_id, $width, $height, $crop) { // Temporarily create an image size $size_id = ‘lazy_’ . $width . ‘x’ .$height . ‘_’ . … Read more

When an image is uploaded in WordPress, it is saved in its original size, and also as some resized copies in different sizes. In this way it becomes easy to use different sizes, of the same image, for different purposes.

Try the following. First, add this piece of code to the template: <?php $image_data = wp_get_attachment_image_src( get_post_thumbnail_id( $post->ID ), “thumbnail” ); ?> $image_data will now return an array containing the url, width, and height (function reference). To get the width, you might do this: <?php $image_width = $image_data[1]; ?> In your specific example, after adding … Read more
