slideshow images don't show up

I selected the image (size: 1000p x 550p) for slideshow but the image doesn't show up on web site.
I see the each slideshow title and even thumbnail image but no main image.

Please help

Make sure image you have selected does not have empty space / upper case in its filename. Also clear any cache in your browser as well as image show gk4 cache folder inside modules/image_show_gk4/cache/.

See you around...
