I can't see anywhere in DPP 3.14 where to add any thing to the image number? OK so I had to find the problem file. add a 2010 date to the end of the file name put it back in to my HD that I store all original images in, reimport it into aperture then take the duplicate named thumbnail and put it back into project where it was suppose to be in the first place. Ugh! How does this duplicate numbering happen in the first place. I'm trying to get my Apertue lib all fixed up so when the new Apple Photo's comes out I have as few problems as possible.
