I also facing the same problem. Lumia 625 Black Update. It is so irritating. I lost many pictues i've taken. When I try to view pictures in my phone via usb in pc (used picasa picture viewer), I found many other pictures other than the picture I have saved. it is about hundreds of gif images, jpgs of kmplayer, google, chrome, softonic, some camera pics i've taken, some pics i've downloaded in phone, many other unknown pics. they are of small size and have file names of the format "vod_thumb_" or "__utm". is it a virus or worm or something?.. or problem with my pc(win8)? any solution? Hard reset the phone (restored settings from cloud) didn't solved the problem.
