My BL-C10A has a http interface that allows urls like
to be used to fetch the image off my local network.
In the Canvas Properties, Graphics TAB I set:
Update interval: 1
Update Base Time 00:00:00
Source Type: 2
Video Feed: [OldVfW]
SourceUrl: (see above in code)
Rest of settings for line 1 are the defaults.
No settings in any other line in the canvas.
In Canvas2 (320x240 netcam image), I have the Graphics Tab use Source type=4 and specify the above canvas as the source. Then in the Text Tab, I put the date/time stamp and imported weather variables on the image along with the boilerplate text. I enabled the Web Server tab to offer up 'netcam.jpg' as the image, refreshed every second. The web server settings are specified by the Internet web server setup for location of the webserver file directory and the port to use, and that's the port I set to forward to the internal IP address of my system from the outer firewall router (Linksys).
In Canvas3 (120x90 thumbnail) I have the Graphics Tab use Source type=4 and specify the raw image canvas as the source. In the Text Tab, I put on the date/time and 'Live' on the image, then enable FTP to push the image to the website every 15 seconds.
