218 Chapter 13 Dynamic Images
Alternate File Location By default, image files are served from a folder relative to the location of the
Image Server application. If you want to keep your dynamic images elsewhere,
pass the -f command line parameter to the Image Server application to specify
the location of the folder. Put this option into a shortcut used to start the image
server, possibly located in the Startup folder of the computer, so that the
shortcut’s Target field reads something like this:
"C:\WATCHOUT 5\ImageServer.exe" -f D:\DynImages
Enclose the image folder path within double-quotes as well if it contains
spaces.
SERVING STILL IMAGES By providing a still image through the Image Server, you may change the
image at any moment. Whenever the image is replaced on the image server,
it will immediately appear on all displays currently showing it. To update the
image on the server, simply drop a new image file into the folder containing
the old one, with the same name and dimensions as the old image.
You can provide the updated image in any way you like. For instance, you
may run a web server on the same computer, configured to allow files to be
uploaded to the image folder being watched by the Image Server. This web
server can provide a web interface for manual uploading of images, or interact
with smart camera phones via the Internet.
Alternatively, you may have a custom application that updates the image on a
regular basis, based on some external data or other events. This application
can run on the same computer as the WATCHOUT Image Server, or another
computer connected over the network. From the Image Server’s point of view it
doesn’t matter where the image comes from. As soon as it is changed, it will
be updated on screen accordingly.
