Introduction to Amazon Simple Storage Service (S3)Go to Lab
A good LAB
The last step did not work the policy was updated but both links showed the latest image.
I have learned very useful things
There's a bug with "Open" the images after clicking the object name, where the image is not displayed. Also, accessing older version of the image via URL does not show different version of the images (this is after having set the bucket policy)
very well explained
