The EC2 Image Locator allows you to find and clean-up Amazon EC2 machine images (AMIs) stored in your S3 buckets. Normally, you create an AMI by bundling up an EC2 instance, storing the content in S3, and then registering the AMI with EC2. When you don't need an AMI any longer, you deregister it and delete it from S3. For a number of reasons, it's easy to lose track of all the AMIs stored in S3, or to find AMI files that are no longer registered with EC2, etc. The EC2 Image Locator consists of a background worker that examines one S3 bucket at a time and locates all of the stored AMI files. A simple S3 browser displays the number of AMIs in a bucket. Only registered images can be migrated to a different EC2 region.

To locate all AMIs stored in this S3 bucket, click the Analyze bucket action button to start a background process that will search for all AMI manifest files and associated image parts. It also checks for image registrations with EC2.

The background process will appear in the Recent Activity pane and may take anywhere from a minute to hours, depending on the number of items in the bucket. Please do not use gratuitously on large buckets! Note that the background process lists the entire content of the bucket, you will thus incur the associated S3 charges. Only registered images can be migrated to a different EC2 region.

Images (AMIs) are EC2 region-specific. If you are using a non-RightImage in EC2-US and would like to launch an instance from the image in EC2-EU, you will need to migrate (replicate) the image. See the tutorial below.
