A while ago, one photo on my iphoto library became corrupted, i dont know how. the thumbnail showed up, but not the full size image. to delete it, i right clicked on it, selected reveal in finder, and put that in the trash. im not sure now why i did it that way, but... i did. so, now iphoto appears fine, minus that one photo, but everytime i sync my ipod with itunes (with photos automatically copying), it says that one or more photos could not copy because they were not found. does anyone know if there is a way to clean up an iphoto library?
