JavaScript: IMAGE object question
(Click here to view the original thread with full colors/images)

In JavaScript, what are the properties of the IMAGE object?
I know very little about JS and have a project that I have to complete soon. We have a video camera on a highway connected to a hardware device that is FTPing the video images to an FTP server that in turn puts the image on a web server. My script is constantly loading the images as they are updated on the web servere and overwriting the image in a browser with the new image. It only updates the image when a successful image load occurs, but while the image is being uploaded to the FTP server, the file size is 0 but the image exists. So, the script downloads the 0 byte image file and updates the browser with the empty image. I need to be able to detect that the image is empty and not update if the file is 0 bytes.
Any ideas?
Thanks,
Scott Harden

The only javascript property for images i know if is image.src but that would not do what you want. Whatever yer doing sounds more like it might take something a little more than javascript. I know cgi can detect if files exist with the -e thing but I dont know if that can even figure out their file size.

ok, I figured out that the properties of a javascript image object are simply the properties of an HTML image (src, height, width, border, etc.) They are the same thing.
