'''Note:''' An image that is in use can not be deleted. Even if no clients are using this image any more, for example having this is image set in a group configuration, even if the group is empty, is considered "in-use" and thus the system would not allow you to delete the file.
== Multiple image pools ==
To avoid large transfers over WAN connections, you can create an image pool at each location, thus reducing the needed bandwidth for updates to one single sync between those locations:
# Make sure that a web server is running on each location
# Setup a folder on this web server containing all of your image files, and keep this folder in sync with the main NTC image pool
# Create a subgroup for each location containing all of its clients
# For each subgroup, point the "Firmwarepool" parameter to the particular synced folder:

'''Note:''' If you're using Microsoft's IIS to serve the image files, please make sure that you've selected "application/octet-stream" for the MIME type of the files to enable the download of the images.
