I managed to get the Dynamic content gallery to work decently, but ended up going different way.
I am using the Post Thumbnail images instead, it is WP core stuff, so I like it better than plugins even though it takes a bit effort to get things done. Later with the posts it is quicker and easier to set photos as thumbnails than to use the custom fields.
Mark Jaquith has a good post in his blog about the Post Thumbnails Images: https://markjaquith.wordpress.com/2009/12/23/new-in-wordpress-2-9-post-thumbnail-images/
Thing is you can enable the thumbnails for posts and pages or just one. I have edited the theme to show the featured content header on everywhere. Then replaced the Featured Content Gallery code with the <?php the_post_thumbnail(); ?> code. The images have been set to 610px X 265px according to the theme featured photo size. Then I edited the Post Thumbnail Image related CSS to match the look of the Featured Content Gallery thing.
What I have not been able to sort out yet is the carousel on the blog frontpage for the featured content, but I blame just my lack of PHP skills for that. You can of course use existing plugin and hack that to use the Post Thumbnail Images from the posts/pages.
I just added “else if” for the blog frontpage to exclude the static post thumb and will put there the carousel when I get it sorted out. ??
