To help end-users identify parts of a package or the package as a whole, images, called thumbnails, may be stored in that package. Each thumbnail image is generated by the package producer and is stored in the package as a ZIP item.

Thumbnail ZIP items shall be identified by either a package-relationship item or a part-relationship item. Packages shall not contain more than one thumbnail relationship associated with the package as a whole, or more than one thumbnail relationship per package part.

example:

<Relationships xmlns="…">
  <Relationship Id="rId2"
    Type="http://…/thumbnail" Target="docProps/thumbnail.wmf"/>
</Relationships>

A Thumbnail part shall be located within the package containing the source relationship (expressed syntactically, the @TargetMode attribute of the <Relationship> element shall be Internal).

A Thumbnail part shall not have implicit or explicit relationships to other parts defined by this Standard.
