(see http://codex.wordpress.org/Function_Reference/wp_get_attachment_image_src) If you don’t know the attachment id you may query the database for full image size url : http://pippinsplugins.com/retrieve-attachment-id-from-image-url/

Your code would look something like this then: function alter_upload_wpse_107016($upload) { remove_filter(‘upload_dir’,’alter_upload_wpse_107016′); // alter $upload array return $upload; } if (1 … Read more
3.5.x Theme Customize: Handling Custom Control Requests
First of all set the image size in Settings > Media or seta customized image size using add_image_size function. New images you will upload will be right size, but for images already uploaded you have to recreate the image sizes, for the pourpose you can use the plugin Regenerate Thumbnails Hope it helps.
