Our gallery organization has changed, instead of using predetermined categories we are locating photos by tags. This is because often cakes could reasonably be placed in multiple categories. So all you have to do is search your desired theme in the search box on the top right of the page. In your search results click the gallery tab to view the images.
You might be interested in other content, such as tutorials or conversation about the same topic, you can find these results under the other tabs in your search results.
