Why doesn't Owen Lars recognize C-3PO during ANH? | As shown in this answer, Owen and Beru Lars should be very familiar with C-3PO (he stayed with Shmi Skywalker till her death, and was present at her funeral).

Why are my recovered images only 160x120 pixels? | I am trying to recover some lost images, and with all the programs I've tried, some of the photos resulted to be in a 160x120 pixel resolution. What does this mean, and is there any possibility to recover photos in original dimensions?
