Lightbox: Do not display pictures larger then 100%

[Akulatraxas]

First of all thank you for putting work into this software. I took me quite some time to find something that fits my needs and pigallery2 came closest. I needed a script that enable/disables login cause i want to present my pictures publicly but otherwise it works great!.

I am not sure if this is a feature request or if I am just too stupid to find the proper option but id like to have the fullview/lightbox view to not display images larger then 100% which makes smaller images on very high resolution screens very ugly.

I do bird and wildlife photography. While a lot of my pictures are big enough sometimes i choose a smaller crop for artistic purposes. The Lightbox scale it up to 2x its size which defeats the purpose.
