Image Checking

[Connell]

Hi,

Sorry if there is a really obvious answer to this.

I have some javascript that uses setInterval(..) to change the src of
an image every second. Is there any way of programmaticall y checking to
see whether an image is loaded properly or if a 404 File Not Found
error occurs for it?

Thanks,
Connell
