photos (with thumbnail) displaying as blank

I have a sony BDP-s580 blu-ray player that has worked well for everything short of subtitles, until now. I tried to create a photo album for my wedding photos and I've had a lot of problems with these jpgs. now my blu-ray player wont display them. I get a black screen when I attempt to view them. They are indexed and they have thumbnails, but viewing them appears to be of some difficulty for my BD player. Using mediahouse on my android phone I had no problem viewing these files. And as my other thread notes, I've had no problem viewing other photos with my blu-ray player, so there must be something strange afoot. Any help I could get is greatly appreciated.
First they wouldn't index by serviio at all... (viewtopic.php?f=5&t=16019)
