There are three (3) different Posts Layouts:

1.) Default Layout

2.) Small Image Layout

3.) Full Content Image

You can set them under Morphis Theme Options > Global Posts Settings > Posts Layouts. Alternatively, if you want to just use a different layout for a specific page, you can just navigate to the Add New/Edit Page of the Blog Page Template and then look for the Blog Post Layout drop-down menu. Here, you can now set specifically for that page the Post Layout you want.
