Is it possible to show Image Name in Title instead of view image

Sure, this is no problem. We will add it to a future version.

For now, simply replace this line of your imaguard.php:

$post->post_title = get_option('ir_page_title');

with

$post->post_title = ir_getposttitlebyurl($_GET['img']);

and then add this function somewhere in the file, f ex between these two lines “add_filter(‘the_posts’,’ir_detectpost’);” and “function ir_createpage()” so you get

(...)
add_filter('the_posts','ir_detectpost');

function ir_getposttitlebyurl($url) {
	global $wpdb;
	$query = "SELECT ID FROM {$wpdb->posts} WHERE guid like '%".$url."'";
	$thisid = $wpdb->get_var($query);
	$postdata = get_post($thisid);
	return $postdata->post_title;
}

function ir_createpage()
