# Sample 1. Step 2: Adding images to the batch

> Add test images to the batch in FlexiLayout Studio Sample 1, set One document per file for reference assembly, and view pages in the Batch window.

<Note>
  A batch is a set of test images (pages) used to debug a FlexiLayout.
</Note>

Once the new project has been created, add the test images to the batch. These images are used to debug the FlexiLayout.

To add the test images to the batch:

<Steps>
  <Step title="Open the Batch tab">
    In the main program window, click the **Batch** tab.
  </Step>

  <Step title="Add the test images">
    In the **File** menu or the shortcut menu, select **Open & Add Images...**.

    </Frame>
  </Step>

  <Step title="Set the reference assembly option">
    In the **Open Images** dialog box, click **Image Preprocessing Settings...**, and then, in the dialog box that opens, select the **One document per file** option.
  </Step>

  <Step title="Specify the test image files">
    The Sample 1 images are located in `%public%\ABBYY\FlexiCapture\12.0\Samples\FLS\English\Halloween Form\Halloween FormBatch\Halloween FormBatch\<page number>\Image\bwPage.frdat`.
  </Step>
</Steps>

The test images you add to the batch appear in the **Batch** window.

<Note>
  When adding images, you can specify how reference assembly is performed. By selecting **One document per file**, you tell the program that each image is a separate document.
