LinPHA PHP Photo Gallery

My "New Images" folder is never empty. I have it set for 15 days. The problem is that I have about 30 images that are always present. The age is different for each one, the first one states the age is "Age: 0 days, 0 hours, 0 minutes and -22753723 seconds" (that converts to 265 days). Even if I set the days to zero, and disable the virtual folder of "New Images", upon enabling it again, the same pictures pop up. Any ideas, anyone else suffering with this? Thanks in advance.
