This may not be an entirely proper place to post this, but maybe someone has some advice?

I've used SlideShowPro and Director to produce slideshows for a site with multiple authors for several years now. For the past couple, it became troublesome that there was no CDN support, but the writing was on the wall. Now that it's been discontinued, I've been looking around for a replacement.

I'm very interested in Juicebox Pro—its slide show interface is most similar to what we produced with SSP, and the way it pulls images from the Wordpress media library is handy, since I've got my library set up on Amazon S3 now.

What I don't like (and I'm hoping there's a workaround for?) is the way galleries are only attached to single posts/pages (correct?)—I'd like to be able to manage galleries separately, and then add them to one or more posts/pages.

I realize I could do this with Flickr or Picasa, but I'd like to avoid going outside the Wordpress back-end again (SSP Director was a separate login, of course, and it'd be nice to move away from that.)

Using NextGEN Gallery is another option, but files uploaded to NextGEN are stored on my server, and there seems to be no support (or reasonable hack) for getting NextGEN to upload to a CDN. So that adds extra bloat with no real benefit—my server's still filling up with photos.

So what's my best bet here? Suck it up, and forget about managing galleries separately?

I've looked at FooGallery, but I'm not a fan of its lightbox display, especially on mobile—even the pro version. But it does arrange photos into galleries that can be dropped into posts/pages with a shortcode. Could Juicebox be tweaked in some way to pull from FooGallery galleries, like it does from NextGEN?

Or—I'm not a fan of this option either, but it might be a compromise—if I had my authors use Juicebox Builder, could we upload the files directly to the CDN, and then point the embed code in Wordpress to them? (Our photos are coming out of Lightroom, anyway...)

Any pointers would be greatly appreciated—especially how I might best be able to wrangle Juicebox Pro into being more what I would like. I've stared at so many gallery plugins and lightboxes that my eyes are glazing over...but I keep coming back to Juicebox...except for that one little hitch. (I'll especially miss being able to group "albums" into "galleries" like we've done here, but the benefit of off-loading a bazillion pictures to a CDN is worth a little creative re-wiring, I guess.)
