I love the plugin, it's exactly what I was looking for. Trying to adapt existing pages with slipshod thumbnail attachments into a proper gallery.
I'm using the simple template with do nothing, when clicked, so the images change with the transitions. I'm trying to get an 80% width, with the thumbnails below the main image being shown, instead of the smaller side-by-side at the moment. It may be me, but changing the columns doesn't seem to do anything, except cause empty spaces in some of the thumbnails.
By tweaking the CSS, I have the thumbnails showing up under the main image, and the width to 80%, but the quality of the image is just that of it being resized and blurry, despite me having thumbnail, medium, or full in the settings.
Any advice on how to make them the requisite quality would be great, and my work will be done.
