I want to reduce the size between an image and the browsers edge. But tweaking the value under "Lightbox|Main image|Images|Padding" does not change that at all. I changed that value to 1 and 100 but the "gutter" is the same.
Sorry, I just noticed this part of code has been inherited from Photoblogger skin which is using ratio (percentage of screen width or height) for the same purpose. So even though the skin has passed the padding, the lightbox used the default ratio instead. I will fix the skin, thanks for pointing out.
