I have saved and named (using Adobe Photoshop) about 150 pictures in a folder in My Pictures in XP. Later when I go back to add some add to the folder from a CD from a relative the original photos in the folder have become mixed up and they seem out of order and the names do not coorespond to the photo. When I view them as a slideshow they are in the correct order, but when viewed as a thumbnail the thumbnail does not coorespond to the name. If I "save as" each picture then they are coorespond again to name, but I'm tired of having to go back and resave each picture all over again. This happens lately to larger folders of pictures that I add to My Pictures. Does any one know what causes this and how to prevent or fix the problem.
