# Playback Mode

The thumbnails in the edit control display the images available in the open image file.

The row of thumbnails support the following features:

- A blue border indicates that it is the SelectedImage and will be copied to the LastRun.OutputImage if you press the Run button.
- A green border indicates the current LastRun.OutputImage buffer, which can be passed to other vision tools for analysis.
- Double-clicking a thumbnail runs the tool and places that image in the LastRun.OutputImage buffer.

When the ImageFile edit control is in Playback mode, you can select stored images with the following buttons.

| Copies the first image in file to the LastRun.OutputImage buffer.
| Copies the previous image in file to the LastRun.OutputImage buffer.
| Copies the currently selected image to the LastRun.OutputImage buffer.
| Copies the next image in file to the LastRun.OutputImage buffer.
| Copies the last image in file to the LastRun.OutputImage buffer.
