I have some pictures off my usbs, memory cards and on my laptop, all JPG JPEG images! Some of them of them are not opening however some are. I have changed the default setting to windows photo viewer that didn't work and then I changed it to paint then restarted the laptop then changed it back to windows photo viewer but still the same problem. What I can't understand is why some files are fine and open but other's are not and the same goes for videos I have aswell. Some open no problem but others don't! Please help!!
