CSS suggestion for easier white frame styling

[Thornos]

This is a little thought of improvement for this neat addon:

.modal-content{
  border-radius: 0;
  background-color: transparent;
  border: none;}

.ekko-lightbox-container img{
  border:4px solid white;}

Compared to other addons I found it rather difficult to adjust something as simple as the white frame around the image. I dont see the need to create the border with a strange background color construct when it would be much easier to do it via border on the img itself.
Maybe this is imported css from bootstrap itself, but this change would certainly make things easier.
If border has too little options, padding would do it too of course.
