I've been building/running self-hosted WordPress sites for years, and never been able to find a slideshow plugin I really like. I've tried a ton of them, and none provides the seemingly basic behavior I want.
Then today I see a WordPress site with EXACTLY what I've always wanted: just show the pictures, in context of the content, with ability to click forward and backward. Turns out it's a default/integrated feature of WordPress.com, requires no plugin and uses the perfect/natural shortcode, and there's no way to replicate it in a self-hosted site.
Is this on the roadmap for self-hosted WordPress,
either core code or as part of Jetpack?
