are pictures from a camera, which I copied with google picasa from the
camera to my home computer. Some of the pictures have been edited
(rotated) with picasa. Then I copied them with rsync to my USB drive.
Now I am looking at them from my work computer.

They do not all have the same permissions, which I don't understand.
The differences to not match those that I have edited with picasa (I
am 95% sure). What should I look for?

Can I somehow set it up, so the files on the USB is readable on any computer?

Are they unreadable on my work computer because I used a cygwin tool
to copy them to the USB, or is all this pure windows?

If I chown the files to my user on my work computer, I can read them
fine, but then I fear I can't read them at home.
