so sorry, another question...
I just installed the lightbox addon and set the image size to 100% but the image quality always worsenes when in the lightbox "mode" (they look softened/not really sharp). But on the regular project page they look totally fine even though they are displayed at an even bigger size than in the lightbox "mode". The height of all of the pictures is 1080 px, I could also make them larger but I guess the size of the images is not the problem, right?
Is there a way to fix this and to maintain the high image quality for the lightbox aswell?
