# Set Preview dialog

It is necessary to set a preview when an image is a stream of pictures. A preview is a picture representing the entire image. A preview is used in the Store Room or when making a wallpaper or a picture in the gallery or when printing a puzzle.

1. Define a preview. To set the preview play an image in the left half of the dialog. When a frame you wish to use as a preview appears, click the Set Preview button.
2. You can repeat former procedure until you find the most suitable preview.
3. Click the OK button.

A preview can be set later when re-opening the dialog by Image->Set Preview...in room main menu
