NextGEN Gallery has a shortcode nggtags that lets you dynamically build galleries and albums from images that have tags; Photocrati talk about it briefly on their working with albums page. One thing the shortcode doesn't do, however, is let you specify a different gallery template for displaying the tagged images. Never being one to shrink from a challenge, my latest release of NextGEN Download Gallery offers a solution.
NextGEN Gallery is one of the easiest to use image gallery plugins for WordPress, so we now try to use it wherever a website needs to have user-managed sets of images: sliders/carousels, trade/media galleries, scenic galleries, you name it. We can do that easily because NextGEN allows you to create custom gallery templates.
Ok, so we're allowed to have one (1) size option for thumbnails in all galleries, and they can be either cropped square, or not. This is my only option? But what if I want to have a gallery page of all of the lovely staff for my clients website, and their photos have been sensibly taken in portrait format, I do NOT want the thumbnails for this gallery to be cropped, that would be just wrong. And then there is to be a page with a photo gallery of the staff picnic where people have enjoyed taking happy snaps in both landscape AND portrait formats because that is what suits, so I need these thumbnails cropped.
