+### Retrieve Docker images
+
+#### Load Docker images
+
+> [!WARNING]
+> This only works when attending a workshop in person.  
+> Due to having a number of people trying to retrieve Docker images at the same time, this allows for a more efficient way.
+
+Once the facilitator has given you an IP address, open `http://<IP-ADDRESS>:8000` in your browser.
+
+When you see the file listing, download the `workshop-images.tar` file.
+
+> [!WARNING]
+> Your browser may block the download initially, allow it to download.
+
 Run the following command:
 
 ```shell
-docker pull ...
+docker load -i ~/Downloads/workshop-images.tar
 ```
 
-> [!TIP]
-> Pulling the Docker images isn't a requirement, but it helps to have it pre-downloaded so we don't wait for everyone to do it at the same time.
+#### Pull Docker images
+
+> [!CAUTION]
+> Only use this approach if you are running through this workshop on your own.
+
+Run the following command:
+
+```shell
+docker pull public.ecr.aws/lambda/nodejs:24
+docker pull public.ecr.aws/lambda/python:3.14
+docker pull curlimages/curl
+docker pull localstack/localstack
+```
+
+### Validate Docker images
+
+Run the following command:
+
+```shell
+docker images
+```
+
+> [!NOTE]
+> You should now see four images listed.
