I am trying to create a gallery with galleria in which when the user clicks on the image (not the thumbnail), a bigger image pops up in a lightbox.

In my view settings, I enabled the lightbox option from galleria options. However, the lightbox-processed image is the same size and not any bigger. After that, I also enabled the "Link image to: file" options in my image field options. This caused all the images in the gallery to display in their original sizes - not in the style that I had selected. Is this a bug?

Is there an alternative way of achieving this?
