# Amazon S3

If your images are stored at a bucket named **mysamplebucket** at the **eu-central-1** region and you can access **image.jpg** at the following URL:

//s3.**eu-central-1**.amazonaws.com/**mysamplebucket**/**image.jpg**

You should enter the data as follows:

All aliases have to be prefixed *and* suffixed by underscores. Please note that all aliases have to be unique for your account - aliases set in the storage sections cannot be used in the [aliases](https://docs.cloudimage.io/setup/shortening-urls/aliases "mention") section.

Your storage container is now accessible by using the alias entered in the *Cloudimage Alias* field:

//your-token.cloudimg.io/**\_\_amazonaws\_\_**/**image.jpg**

If your S3 bucket requires authentication, you can enter your access key ID and secret access key:
