What does the actual HTML look like if you use view source in FireFox? Just
show the few lines with the image element if it's a large page.

Here is the body of the actual HTML:

<body style="margin:0;">

<form name="aspnetForm" method="post" action="default.aspx"
id="aspnetForm">
<div>
<input type="hidden" name="__VIEWSTATE" id="__VIEWSTATE" value="/
wEPDwULLTEwMDUyNjYzMjhkZDb/t/kquMagf1RBrd1IArHZAeT+" />
</div>

<div>
<center>
<table style="width:100%; background-color:Black; height:75px;"
cellpadding="0px" cellspacing="0px">
<tr>
<td >
<img id="ctl00_image1" src="Images/Banner.jpg" alt="banner"
style="border-width:0px;" />
</td>
</tr>
</table>

</center>

</div>
</form>
</body>

Seems fine and works for me. Do you have some sort of banner blocking
add-in?
Is this on a public site where I can try it?

I run the website from local host and I think that fire fox blocks
images from local host, but don't know how to solve this problem. do
you have any idea how to solve it?

thanks Joe.

I solved the prblem

The problem was that firefox stored the images in the cache. sol i had
to clear the cache before loading the page, in order to view the
image.

I solved this problem by changing the image url randomly, so there
would be no image in the cache which had the same name.

I added this code to the page load event of the master page:


protected void Page_Load(object sender, EventArgs e)
{
Random rand = new Random();
int num = rand.Next();
Banner.ImageUrl = "~Images/Banner.jpg?" +num.ToString();
}


thank you for helping
