The WATCHOUT Dynamic Image Server is a separate program that allows you to incorporate up-to-date text, images and graphics into your presentation. It renders the requested images, and sends the result to your display computers via the network. This is somewhat similar to the way a VNC Server provides images for a “Computer Screen” media item, but provides greater flexibility and programmability.
IMPORTANT: As the Image Server runs as a separate application, it requires its own WATCHOUT license key.
The Image Server can serve three types of content:
- A still image
- A web page, based on standard HTML5 components
- A SWF file (Adobe Flash)
For still images, the Image Server accepts JPEG and PNG and TIFF formats. It supports transparency information in PNG and TIFF images, as well as in HTML and Flash content. See “Add Dynamic Image” for more details on how to configure this media type.
Alternate File Location
By default, local 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 resembles the example below:
“C:\WATCHOUT\ImageServer\ImageServer.exe” -f D:\DynImages
If the image folder path contains spaces, enclose it within double-quotes too.
