There is repeated logic in the function for fetching metadata and images from IPFS. This logic could be refactored into separate methods to adhere to the DRY principle and improve code maintainability.

An example of how the refactoring could look like is provided below:

// Example refactoring for fetching metadata and images from IPFS
func fetchMetadataAndImage(client ipfs.Client, fetcher metadata.MetadataFetcher, id uint64) (*bytes.Buffer, error) {
    metadata, err := fetcher.Fetch(id)
    if err != nil {
        return nil, fmt.Errorf("Failed to fetch Metadata for ID %d: %w", id, err)
    }

    image, err := client.GetImageFromIPFS(metadata.Image)
    if err != nil {
        return nil, fmt.Errorf("Failed to retrieve image from IPFS for ID %d: %w", id, err)
    }

    return image, nil
}

This issue was created following a discussion in PR #27.

There is repeated logic for fetching metadata and images from IPFS within the function. This logic could be refactored into separate methods to adhere to the DRY principle and improve code maintainability.

A committable suggestion was provided in PR #27, which should be implemented to reduce redundancy.
