Show Off Your Dashboards!

Longtime lurker, finally have my dashboards done after kicking the contract alarm company out and installing Konnected boards. Pretty satisfied overall, but one item keeps driving me nuts: if I copy the link of one of my images from my Synology NAS Photo Station as a dashboard background, it works on my desktop PC. However, it won't display on the Fire 7 tablet I'm using as the wall panel. If I upload my photo to Google photos and use the image link from there they work just fine, but I'd really like to get it to work locally rather than rely on Google for hosting.
