Resource Manager
The Resource Manager is used to centrally manage all of the images in the document, where a single image can be reused across sections without needing to import the image into the document multiple times. The Resource Manager can be accessed by opening the Tools menu and selecting the Resource Manager menu item. The Resource Manager window appears as shown in the following screenshot:
The Resource Manager window has a toolbar at the top with buttons for adding a new picture to the document and for changing the view of the list of pictures in the main section of the window. Right-clicking on a picture brings up the following list of options for modifying and maintaining the object:
Replace provides the ability to update the image with a new picture, updating the picture throughout the dependent sections with a new picture.
Merge Duplicates provides the ability to merge the multiple copies of a picture in the document with a single version of the image.
