Hey looks like there's a bug on the slider on mobile; after a couple of pictures there a photo that tells you (x more photos) over that current image that makes some transparency thing on it.
it works nice on desktop version but, it should be disable on mobile since you see it one by one.

thanks.
 

Do you have screenshot?

Nice catch, thanks.
Please go to responsive.css and bellow this line:

@media screen and (max-width: 767px) {
Add:
#listing #pictures.t5 a.c5.more-img span {display:none;}
