No, please refer to the images I included in the first post. There is no "type" drop-down for me to select a slideshow in the gallery. I use your templates and know how to insert a gallery, I'm just wondering what happened to the slideshow?

 

Hello,

There is some problem with the new gallery of WordPress.
It is not a theme issue.
You can check it by activating WordPress default theme.
