You could access these images before? Did you try turning your Xoom off, then on?
What model Xoom? I have the Wi-Fi model using Android 4.1.2.
Thanks guys but still no pic.Have found by going into gallery and selecting pic I can then select edit . PS Touch then comes up on the list of choices so I can at least work on my photos now. XOOM using android 4.1.2
