In the admin mode, you can search for image annotations:
<?php echo simple_search("Search", array('id'=>'simple-search'), uri('image-annotation/moderate/browse')); ?>
Is there a way to search image annotations in the public view without adding the image annotation browse.php file to the public folder? I was thinking that there might be a way to add an annotation search to the advanced search page, something similar to the tag search on that page.
