     The name you apply to the file should match the original file, so as not to confuse the mailing recipient.

## Categories

Click the **Images** tab to display images, or the **Attachments** tab to display attachments.

### Images

The **Images** overview displays the following information:

- **Name**. The file name.
- **URL**. Where the image is stored. If it is physically uploaded to Optimizely Campaign, the URL is an internal URL (http.//img.example.com/...). If you selected **External URL**, the file's original URL is shown.
- **Location**. Indicates whether the image is stored on Optimizely Campaign (server) or located externally.
- **Dimensions**. The image's dimensions in pixels.

:::hint{type="info"}
**Tip**

Select an image in the overview to display an image preview.

### Attachments

The **Attachments** overview displays the following information:

- **Description**. The attachment description.
- **File Name**. The file name.
- **URL**. If you selected **External URL** while importing the attachment, the file address appears. If the file was physically imported into Optimizely Campaign, this field is empty.
- **Location**. Indicates if the file is stored on the Optimizely Campaign (server) or located externally.
- **Type**. The file format (PDF, DOC and so on). This is the original file format as recognized by Optimizely Campaign when the file was added, not the format you applied while naming it.

  :::hint{type="info"}
  **Tip**

  The type you apply to the file should match the original file, so as not to confuse the mailing recipient.
  :::
- **Size**. The file size in bytes. Use discretion with the file size, so recipients are not annoyed by large attachments.

# Adding Images

To add images and use them later as mailing attachment in Optimizely Campaign, do the following:

:::hint{type="info"}
**Note**

The image's file format must be .gif, .jpg, .jpeg or .png.
:::

1. Open the Optimizely Campaign menu and select **Campaigns** > **Images and Attachments**.
2. Open the **Images** tab and click **Add…**.
3. Select one of the following options:
   - **Upload**. Click **Browse…** and select a file from your computer. The image is still available even if your local version no longer exists.
   - **External URL**. In the **URL** text field, enter the web address where the file can be found, beginning with `http://`. The image is not physically imported into Optimizely Campaign. Mailings include only a link to the image.
4. In the **File Name** text field, enter a name that helps you recognize the image when creating a mailing or in the content overview.
5. Click **Save**.

# Adding Attachments

To import files into Optimizely Campaign and use them later as mailing attachment, do the following:

1. Open the Optimizely Campaign menu and select **Campaigns** > **Images and Attachments**.
2. Open the **Attachments** tab and click **Add…**.
3. Select one of the following options:
   - **Upload**. Click **Browse…** and select the desired file from your computer. The file is available even if your local version no longer exists.
   - **External URL**. In the **URL** text field, enter the web address where the file can be found, beginning with `http://`. The file is not physically imported into Optimizely Campaign. Mailings include only a link to the file.
4. In the **File Name** text field, enter a name that helps you recognize the file when creating a mailing or in the content overview. Maintain the file extension (.pdf or .doc) so recipients recognize the file type.
5. In the **Description** text field, enter a file description.

   :::hint{type="info"}
   **Tip**

   The description is used internally and is not part of the mailing.
   :::
6. Click **Save**.

# Sending personalized attachments

The **Personalized attachments** feature lets you include attachments to particular recipients when sending transactional mails. For example, you can send invoices or order confirmations.

Before sending, transmit the attachments to Optimizely Campaign via [HTTP API](docId\:T_lQHGWpBhNrdvooGdrdw) or [REST API](https://api.campaign.episerver.net/apidoc/index.html#/Attachments/createAttachment_1).
