“ePhoto was created for those looking to turn their blog into a photo gallery. While the theme was created with photographers in mind, it can certainly be used to display any type of digital imagery. While the main content of the theme is image based, there is also the ability to create separate blog pages where normal blog posts can be integrated with your photos.”
