How to set the Interval distance between slice node layout grid?

i use yellow window to show 1x6 grid layout of a T1 volume

is it possible to set the inteval distance between the 1x6 grid layout below?(PS. the default value is 1 layer distance i found from data probe)

We plan to remove this lightbox view feature, because it is slow and limited to image display. Instead, try the lightbox mode of Screen Capture module.

thank you lassoan, i agree screen capture is a very good feather , but our boss and the doctor like the effect of lightbox view feature , maybe i need to read the corresponding code next . :sob:
