    Default iPhone 5 in USB Port and Image File Modification

    I recently used a USB port on my Windows 7 PC to charge my iPhone 5. I affirmed the question 'do you trust this computer' even though I had no new photos to download. I should add that I only have iTunes installed on the iPhone and not on the PC.

    After 45 minutes I released the USB connection and soon discovered that about 3500 jpg and png files all had new Modified On dates. Further investigation of selected files showed me that the 'modified' files were often larger, sometimes by as much as 25%.

    1) Has anyone got any idea what is going on?

    2) If so, what do I do to avoid this in the future?

    I do not want to restore the structure of my image files (and recover from any jpg quality loss) only to have the same experience another time. I would like to be able to download photos from my iPhone.
