When I'm viewing an image in the Fancybox, the background is grayed out to obscure it a bit. I love this feature, and I would love for the background to get even whiter so it's even more obscured. I found all of the image files in 'mywebsite\wp-content\plugins\nextgen-gallery-optimizer\fancybox' and I tried editing the png files in Photoshop and re-uploading them. I was able to change the color of the 'close', 'next' and 'previous' icons by editing 'fancybox.png', but I can't seem to figure out how to edit any of the other pngs so that the background gets whiter. Can someone point me in the right direction?
