22891,WordPress Filter media_buttons_context is Not Working in WP Version 3.5,onetarek,,"I am using the filter 'media_buttons_context' to add my custom media button beside the media upload button in the post/page editor. 
After updating wordPress to version 3.5 my button is not being shown.

My codes are bellow:
{{{
<?php
function wp_myplugin_media_button($context) {
	$wp_myplugin_media_button = ' %s' . '<a href=""media-upload.php?type=upload&TB_iframe=true&tab=upload"" class=""thickbox""><img src=""http://onetarek.com/wp-content/uploads/2012/12/shortcode_btn.png"" width=15 height=15 /></a>';

	return sprintf($context, $wp_myplugin_media_button);
}

add_action('media_buttons_context', 'wp_myplugin_media_button');
?>
}}}
