plz some one help me on this code...,

回答1:

The problem is that you are using an address to an image on your computer, so that will only work when you view the page from that specific computer.

You should copy the image into the web application, for example into a folder named images, then you use that address in the image tag:

<img alt="" src="images/images4.jpg" />

回答2:

Your image should be in the folder accessible to your web server. Try including your image into your solution file (assuming you are using Visual Studio), and use relative path, such as "/images/image4.jpg"

Go to some web site (like www.cnn.com), view source for any page and see how they set path to img tags.

You can also use ASP.Net image tag, check out MSDN for examples and usage.
