|When you insert an SD card into a computer it will come up as (or in) a specific drive in "My Computer".|
It will also create a pop-up for handy use (AutoPlay).
We need to decide which of these is the situation. Go to "My computer" with the card inserted and see if there is a small drive which contains your pictures. They will usually be in a DCIM folder and you should be able to double click each picture to open it.
If that works we can look at the AutoPlay issue.
Always pop back and let us know the outcome - thanks
