2. Yes – more specifically, does the particle work with the routines already present in grav to generate thumbnails and pictures of required sizes, for example retina versions if the source file is “big” enough
3. I’d like to achieve two things:
3.1 use the alternative lightbox photoswipe, which i installed as a plugin to grav
3.2 use the portfolio for linking to albums and for the pictures in the albums. in the first case, no lightbox should open or even be linked to. in the second case, only the lightbox.
