Conditionally showing navigation arrows

Hello.

After a couple of years i came back to your plugin.

I switched on Lightbox for “WordPress Iimage-Links” and i included data-rel=”norl” in the <a—-> clause for certain huge (and i mean huge) images which open in a new tab.
So far so good.

On one page a have several posts with images, videos and so on and two interactive swf-files. I had to switch off the navigation arrows in the global settings as otherwise the lightbox switches to the next picture (from the next post on this page) instead of being controlled.

On an other more static page i have a gallery where i want the navigation arrows back. Going through the pics with the cursor keys is working, but no longer with the mouse.

Is there a way to switch off or on the arrows individually?

Thanks in advance.
