Thanks, this does look interesting. I will review the demos over the weekend. I'm not nuts about uplifting everything from my website. Photocrati as it is works for me because my main focus is setting up galleries rather than blogging or creating fancy pages.
With Photocrati + Nextgen Pro I use two additional plugins to help with enabling clients to download digital images:
Smart Passworded Pages
NextGEN Download Gallery
Nextgen Download Gallery uses a template with one of the original NextGen (not Pro) galleries to layout thumbnails and select individual, several or all photos (and I've adjusted the script to control resolution). It's a nice package that zips up all photos selected and provides one file for download. The problem, the latest NextGen Pro update broke its functionality, the download gallery plugin doesn't work anymore. By the way, it's not uncommon for NextGen updates to break other plugins, or even alter its own features. Very frustrating.
I was given a beta version of NextGen Pro which now includes code to offer free downloads, but once again they really didn't think it through - it's either all or nothing. I can't direct a client to a confidential page so that only their images are available. Sigh.
I've been exploring another gallery plugin, Envira, that looks great. In addition to (I think) the functionality important to me, it's got great sharing capabilities and Lightroom integration. As well, apparently there is seamless migration from NextGen to Envira galleries (very important). Themegoods may as well, I haven't looked into it as thoroughly. Another benefit to Envira, WooCommerce (probably the best there is for ecommerce) is fully compatible.
Setting up a website is rewarding but it's a tremendous amount of work. I really don't want to completely redo everything, but I need to find a permanent solution that is easy to manage and update without struggling to maintain every time a theme or plugin changes. Photocrati/NextGen are making this very, very difficult lately.
