What operating system are you using?
Thank you for the information. Please give me some minutes to investigate.
While I do that please try to drag one of the photos form the memory stick and drop it on any folder in your computer and try to open it from there.
Ok let us try this procedure:
1. Go to: ***** ***** >> Programs >> Default Programs >> Associate a file type or protocol with a program
2. From the list scroll down and select .jpg JPG File
3. After selecting .jpg click "Change program ..." button on the top right corner of the window.
4. From the list that pops up select "Photo Gallery" and then click Ok
5. Restart the machine
Try to open them again and let me know if this solves it.
Did the procedure wok?
