There are two categories of images in a Dr.Explain project:
1. Images directly imported into a Dr.Explain project
screenshots (primary image in a screenshot layout page) brought in via screen capture, image file, or via image on the clipboard;
regular images, brought in via screen capture or from image file (into either basic or screenshot layout pages).
2. "Control" images automatically derived from a screenshot (one for each callout) in a screenshot layout page.
The images in category 1 however have a universal way of controlling their size and boarders via right-clicking the image and selecting Image Properties.... Screenshot images may additionally be have size, cropping, and text labels modified via the Annotation Designer.
The images in category 2 are directly extracted from the screenshot image. Limited control is available for these images by changing the size and shape of the control area using the Annotation Designer.
