so right now I have 3.65g of images and video, it's on my one drive and I'm not sure if that has a factor here or not, but I'm not able to go through in the picture viewer anymore, it will get to the image in the folder that doesn't have thumbnail and suddenly act like it's the only photo in the entire folder. if I try to open the next photo with no thumbnail it loads forever.I noticed that if I open the image in paint, and save over the photo itself that one picture is fixed. but how do I do that for a whole 3 gigs of images without wanting to blow my brains out for the monotony? like is there an image fix program? they are all saved in normal extensions (.jpg, png, gif,bmp)
