Is it possible to put a white image border around the photo when it shows up in the lightbox mode on a gallery block. I don't save the image with a white border because I use square thumbnails in the grid display of the gallery block and saving the image with a white border would show white borders only on two or three sides since the image is cropped to a square.
It would be great to have this as an option or if there is some custom code that could be embedded on the page.
