Hi! I use the werkstatt theme for a website and wanted to follow up on a question I posted last week:

In the category tiled gallery view I ran into some problems with the mixture of landscape and portrait format images: sometimes the gallery has big holes of white space in between. Is there a way to fix this? You were asking me to provide the link and here it is: http://troublemakerstreet.com/index.php/category/wedding-photography/

How can I solve this?

Thanks! Best Stephanie
