I have asked this question of the JAVA people.
I have a cam FTP uploading a file called cam0.jpeg a couple of times a second to a web server.
This is something you see all over the web. Like http://www.earthcam.com/usa/newyork/timessquare/
Usually then flash or a Java applet refreshes the image.
My problem is the image is always broken because the file is being constantly uploaded.
Can Flash be made to view just one file constantly changing at 1-2 frames a second without viewing the half loaded images?
I still haven’t really got a definitive yes or no.
