リッチテキストの中に画像をアップロードするにはアマゾンS3のアクセス許可の設定をしなければなりません。
アクセス許可のタブの下部にある「Cross-Origin Resource Sharing (CORS)」の項目に以下の記述を追加して保存します。

[
    {
        "AllowedHeaders": [
            "*"
        ],
        "AllowedMethods": [
            "PUT",
            "POST",
            "DELETE"
        ],
        "AllowedOrigins": [
            "*"
        ],
        "ExposeHeaders": []
    }
]



画像のアップロードはこれでできるのですが、表示させるには「mini_magick」と「image_processing」をインストールする必要があります。
GemFileに以下の記述を追加して下さい。
