You can exclude images from being included in the generated sprite and CSS but still allow them to be part of the Spriter project
If an image is excluded from output, it does not appear in the generate sprite, CSS or HTML. However, any effects which are sourced from that image will continue to be displayed, unless the Include Derived Images option has been selected.
Using the Image or Files views, either context click an image and choose Properties
- or -
from the menu, or double click an image
From the Properties dialog, check the Include in output box
Click OK to save your changes, or Apply to save the changes and keep the properties dialog open
In the Files view, check the images you wish to include
