The code below is setting up the reply for an inline attachment:. The source code shown here is based on the Handling attachments sample. To send the user a single piece of content like an image or a video, you can send media in a few different ways. First, as an inline attachment:. The source code shown in this section is based on the Handling attachments sample. The getAttachments method of the Activity object contains an array of Attachment objects that represent the media attachments and rich cards attached to the message.
If an attachment is an image, audio, or video, the Connector service will communicate attachment data to the channel in a way that enables the channel to render that attachment within the conversation. If the attachment is a file, the file URL will be rendered as a hyperlink within the conversation. Besides simple image or video attachments, you can attach a hero card , which allows you to combine images and buttons in one object, and send them to the user.
Markdown is supported for most text fields, but support may vary by channel. To compose a message with a hero card and button, you can attach a HeroCard object to a message. To process events within rich cards, use card action objects to specify what should happen when the user selects a button or taps a section of the card. Each card action has a type and value property. To function correctly, assign an action type to each clickable item on a hero card. This table lists and describes the available action types and what should be in the associated value property.
The messageBack card action has a more generalized meaning than the other card actions. See the Card action section of the Activity schema for more information about the messageBack and other card action types. For examples of all the available cards, see the Using cards sample.
While you can use the message factory to create a message that contains an attachment of any sort , an Adaptive Card is one specific type of attachment. Note that some channels don't support Adaptive Cards, and channels that do may only partially support them. For example, if you send an Adaptive Card in Facebook, the buttons won't work while texts and images work well.
Adaptive Cards are an open card exchange format enabling developers to exchange UI content in a common and consistent way. However, not all channels support Adaptive Cards. The Adaptive Cards Designer provides a rich, interactive design-time experience for authoring adaptive cards.
You should test this feature with the channels your bot will use to determine whether those channels support adaptive cards. The source code shown here is based on the Using cards sample. Messages can also include multiple attachments in a carousel layout, which places the attachments side by side and allows the user to scroll across.
Then add the attachments and set the layout type to carousel. Here we're adding them one at a time, but feel free to manipulate the list to add the cards however you prefer. Add the attachments and set the layout type to carousel. Once the attachments are added, you can send the reply just like any other.
The source code shown here is based on Using cards sample. The following sample shows one way to use Adaptive Card inputs within a bot dialog class. It extends the hero cards sample by validating the input received in the text field from the responding client.
You first need to add the text input and button functionality to the existing adaptive card by adding the following code just before the final bracket of adaptiveCard. Note that the ID of the text input field is set to "text".
When the user selects OK , the message the Adaptive Card generates will have a value property that has a property named "text" which contains the information the user entered in the text input field of the card.

Under the Image Attachments section, select Resize large images when I send this message.

To help reduce the size of attachments that you send in Outlook, see Reduce the size of pictures and attachments. In addition to mail provider limits on total message size, sending large attachments through email is not always the best solution. Your message might cause your mailbox to exceed the storage quota Each message that you send is saved in the Sent Items folder. Sending large attachments to other people counts against your mailbox size quota as well.
When you exceed the storage quota, you could be blocked from receiving additional messages. Attachment bloat When a file is attached to message, it has to be encoded. The encoding process causes attached files to become 1. For example, if you send a 5 MB file attachment, the attachment is sent as 6. There are several ways to share large files and collaborate with other people without sending attachments. For more information, see Save a file to a SharePoint library. SharePoint libraries can be accessed directly in Outlook.
