Adding a photo to a character
Each character can have one photo.
Photos can be added through an open file dialog. With the open file dialog, it is possible to add an image to a character by locating the image file
and clicking Open.
There are two ways to display the Open file dialog:
Select Choose Character Image from the Edit menu.
Double-click the character image field under Create view mode.
The photo size on screen is 150px x 150px. In print, it is 200px x 230px.
Note: The image you choose will be stored at the original size, so large megapixel pictures will bloat the file size quickly.
