Analyzing gallery layout I've found div container for thumbnail (together with caption) with class image-thumbnail-view assigned.
This comes from theme/gallery-image-thumbnail.php.tpl, where you can find:
<div class="image-thumbnail-view <?php if ($type) print "image-thumbnail-". $type?>">
but this class does not exist in any css file
