Hope you get the problem sorted.
I saved some pictures to a cd and when i tried to view them they will not open. When I open the cd it shows files currently on cd is my albums. When I open that folder it shows 24 files that are named
camera 3-22-2005 and so on. The files range in size from 7 kb to 35 kb i am sure that these are all the pictures that i took in key west. It says the type of file is a pvm file and that it opens with hp imaging zone but i can not open with that or any other program. I have tried everything do you have any ideas. When i created this cd i put other pictures on other cds and they are fine. This is the only one that saved as a pvm file and i backed up all of the picture the same way.
