Media Resource
The Media resource represents a piece of media, such as an image, that is associated with a message.
Twilio will create a Media resource and store the contents of the media when the following events occur:
- You send a message with an image via Twilio
- You receive media on one of your Twilio phone numbers
Twilio will keep that media around until you issue an HTTP DELETE on that instance.
To secure access to media stored on Twilio, you can enable HTTP basic authentication on the Console settings for Programmable Messaging.
Messages sent via Twilio can include up to 10 media files that have a total size of up to 5MB. Twilio will resize images as necessary for successful delivery based on carrier specifications. Messages with over 5MB of media will not be accepted.

Because the stored media URLs are useful for many external applications, they are public and do not require HTTP Basic Auth to access. This allows you to embed the URL in a web application without revealing your Twilio API credentials.
If you have a need to restrict access on media stored with Twilio, you can enable HTTP Auth on the Console settings. When you fetch your message media after enabling HTTP auth, you will be directed to a signed URL that is only valid for 4 hours.
You can make subsequent API requests for new short-lived URLs for your media at any time.

ヒントとテクニック
- Twilio will attempt to cache the media file the first time it is used. This may add a slight delay in sending the message.
- HTTPヘッダーが許可している（EtagおよびLast-Modifiedヘッダー経由）場合、Twilioはファイルのキャッシュを行います。
Cache-Control: no-cacheを伴ったレスポンスを行うと、Twilioはファイルが変更されたかどうかを常に確認するようになり、ご使用のWebサーバーが新しいバージョンのファイルでレスポンスするか、それとも403 Not Modifiedを返してTwilioにキャッシュされたバージョンを使用させることができます。
