Make your own online window. Basic web page skills required.
1) Get some free webspace. (Free
is available for all amateurs, there are many other places.)
2) Set up a page in your web space with an image of
appropriate size. Make sure the image is called: Grabby1.jpg
3) Install Grabby
configure image store in a known location on your PC.
4) Install a timed FTP uploader from folder on PC and
overwrite the image on host at set periods. I used 'AUTO FTP
V2' - free search online as links change
5) Fiddle about with the timings - patience required.
There must be a million other ways, but this was free and
simple, just like me ;-)
