Using the Invoice Verify module, select > to view the images of the appendices belonging to a particular invoice.
To see an invoice's appendices, click the tab at the bottom of the invoice view. The appendices are displayed as small images.
You can double-click a small image to view the appendix image full-size. You can then zoom in on the image, and move the image, the same way as for an invoice page.
You can also change appendix pages to invoice pages, or vice versa.
