Hi, many of my Wiki's images, especially structural images have transparent backgronds. I created a slider on this page http://health-and-medicine.wikia.com/wiki/Category:1ITF that gives all the images in the gallery a black background, I'd like to know how to fix this (e.g., set this to white). Additionally, some of these structures have two views (bird's eye view and side view) and I'd like to know how to show each of these views side-to-side whilst still using a slider type of gallery.
