If you look at the home page of this demo site, just under the featured articles, you’ll see thumbnails for the 4 most recent photos galleries. To add the photo gallery thumbnails to your own site, you only need to do 3 things …
1. Create a new post, upload your images and insert your gallery into the post.
2. Tag the post with the tag “gallery.”
3. Visit your Theme Settings page, and select “yes” where it says “Recent Photo Galleries on Home Page.” The theme will do the rest.
If you want images displayed using the image-php template, in addition you need to link the gallery to “Attatchment page” and not have any lightbox plugin activated.
