The Total theme has a built-in image resizing function that crops images only as needed instead of the core WordPress post thumbnail function which crops images to every defined size whenever you upload a new image. For this reason Total has it’s own helper functions for returning images in the theme which you can make use of in your child theme if needed/wanted.
Here is an example:
$thumbnail = wpex_get_post_thumbnail( [
'post' => null, // (int) Fetch thumbnail from a post.
'attachment' => '', // (int) Fetch thumbnail from a specific attachment ID.
'size' => '', // (string) Pre-defined thumbnail size name (thumbnail, medium, full).
'width' => '', // (int) Custom width.
'height' => '', // (int) Custom height.
'crop' => '', // (int/string) Crop location.
'return' => 'html', // (string) Function return html, url, src.
'style' => '', // (string) Custom inline style attributes (padding:10px;).
'alt' => '', // (string) Custom alt.
'class' => '', // (string) Custom classnames.
'before' => '', // (html/string) Content to add before the thumbnail.
'after' => '', // (html/string) Content to add after the thumbnail.
'attributes' => array(), // (array) Custom html attributes.
'add_image_dims' => true, // (bool) Add width/height attributes?
'schema_markup' => false, // (bool) Add schema markup?
] );More helper functions:
