wp_get_attachment_image_src returns incorrect URL on multisite
I found this stray code in the header.php $GLOBALS[blog_id] = get_option(‘woo_blog_id’); This wiped out the global variable that get_current_blog_id() relies on to get the site id in multisite.

How to obfuscate theme directory URLs
Use get_template_directory_uri(): $url = get_template_directory_uri() . ‘/images/myimage.jpg’; This function will always return the correct path to your theme. If you want to hide/shorten that URL, you could use an endpoint, maybe img. The downside is, you load the complete WordPress for each image request. Or use mod_rewrite: RewriteRule ^img/([a-z\d-])\.png /wp-content/themes/my_theme/img/$1.png [L] This will not work … Read more

What can i do add title to ‘large’ image?
Check the Codex. the_post_thumbnail accepts two parameters, the second of which is $attr— “attributes”. the_post_thumbnail(‘full’,array(‘title’=>’yay! a title!’)); The Codex entry for the_post_thumbnail is not clear on what is and is not allowed as an “attribute” but it appears to depend on wp_get_attachment_image and by filters applied by that function. title does work though.
