7. Upload your images: `ardrive upload-file --local-path /your-images --parent-folder-id <DRIVE_ID> --wallet-file your-wallet.json`
8. This will put `your-images` in your Drive.
9. Create a Manifest: ardrive create-manifest -f <DRIVE_ID> --wallet-file your-wallet.json
Great! Now all your images are accessible in that single directory. e.g, https://zk2wipqvqlavjz3tdh4hz6ibye3w5anz3b7bqbed3oqbzyoqnncq.arweave.net/yrVkPhWCwVTncxn4fPkBwTdugbnYfhgEg9ugHOHQa0U/images/999.png
NOW DO THE WHOLE THING AGAIN WITH YOUR JSON, and finally set that root directory as the baseURI on your contract.
