i'm not sure how you can request my doubt... i'll attempt to make my question easy...

i produced a brand new html file and attempted to transform it into wordpress theme.. after i attempted to incorporate the files (image,js or anything) using "/sub-directory/filename" it's not including... after i change it out into "http://localhost/wordpress/wordpress-content/styles/ashok/sub-directory/filename", it's working fine...

i'm not sure what's the problem... can u help me...

<?php bloginfo('template_url'); ?>/images/image.png

Works together with all sorts of file. If you want to incorporate a template part, let us say search-form.php use:

<?php get_template_part('search-form'); // So, without .php extension ?>

Try:

"<?php echo get_bloginfo('stylesheet_directory') ?>/sub-directory/filename"
