Why does a black gallery wallpaper have ghost thumbnails that are only visible on vertical (portrait) images (These shadows are hidden when the images are in landscape format)?
Is it possible to send you a screen coy?
Can you post a link to an album?
You can add screen shots to posts by copy/paste
It’s probably some transparency in the Slideshow Backdrop
You can see it here Bronces Les amoureux de Peynet Photography - John Bronces

I can see the thumbnails, very faintly.
I think it’s the transparency in the Slideshow Backdrop.
In your page template, go to Slideshow > Backdrop
click on the color drop-down. My guess is that the transparency slider is allowing some transparency. Slide it all the way to the right.
