I have a "target" collection of photos that were taken on a black back ground. When sending the Lightroom mobile link via email to another person and that person opens the files on there own computer they show up on a black screen thus all the pics are blending together. Is there any way I can alter the screen background or automatically create a light colored frame around the pics in order to distinguish the pics from the background?
No, you can't customise the appearance of Lr Web pages, if that's what you're asking.
Thanks for your help!
