Question about Pull Image script
The following is a pull image script used with webcam32. I want to write my own app to return an image each time it is requested but I cannot figure out the way it requests an image. I have a web server control in VB and I can load any pages or images. I tried that when it requests just pull I return an image but its broken and stops. Can someone who knows about this tell me what way I need to return an image?
Thanks!
Code:
<html>
<head>
<title>Image Pull</title>
</head>
<body>
<H1>This is the client pull sample</H1>
<TABLE border=1 cellPadding=1 cellSpacing=1 width="75%">
<TR>
<TD height=300 style="BACKGROUND-COLOR: lightyellow; HEIGHT: 300px; WIDTH: 300px" width=300
align=middle vAlign=center>
<script LANGUAGE="JavaScript">
<!--
browserType = navigator.appName;
newImage = new Image();
document.onstop = document_onstop;
