1. Add the picture to your page, using a Picture widget (located in Widgets and selecting Popular from the drop-down menu).
2. Hover over the Picture widget and click Edit on the top left corner of the widget.
4. The Link Editor dialog box will open, add a link to one of the four categories and then click OK.
6. To check that your link is working, preview your page and then click on the link.
Hint: If you insert your picture in a Text widget (instead of a Picture widget) you can turn it into a link by selecting the picture and then clicking the "Link" button (looks like a chain link) on the Text Editing Toolbar. From there, follow the same steps as outlined above.
