There are literally hundreds of posts on net about this problem -- but no solution so far as I have been able to determine. Some of my jpeg images open with windows picture and fax viewer and some show no preview available. All open in Photoshop without any difficulty. All are associated with Windows picture and fax viewer, all are roughly the same size and the fact that all open in Photoshop with no artifacts or flags says all are uncorrupted. I am running Windows XP with SP3 installed. I have opened an image in Photoshop that had no preview using Windows picture and fax viewer, saved it as a jpeg image which then opens in Windows picture and fax viewer as it should. Go figure! This is a very common problem, so there must be a simple solution. Anyone know what that is?
