I am using the

geodir_get_featured_image($post['ID'], 'thumbnail', get_option('geodir_listing_no_img'))

to return the Featured Image, but it always return the default size Image & neglecting the thumbnail attribute.
How to get Featured Image with Particular Dimensions ?

<?php the_post_thumbnail( $size, $attr ); ?>

Please see: https://codex.wordpress.org/Function_Reference/the_post_thumbnail

Thanks

I am not using the post loop, I am using the

geodir_get_featured_image()

in a REST API to get the Image.

I must say the Geodirectory Functions are kick-ass & able to create the REST APIs by utilizing them. Just got stuck here about retrieving POST featured Image with specific dimension.
