Images not displayed

[jimberry]

Has anyone had problems getting images to display due to programs like Norton Antivirus rewriting html after it is downloaded from the server?

On http://bppdocs.camner.net/html/screenshots/style_screenshots/style_examples.htm

If I view this page in any browser (IE, Firefox, Netscape) on my XP system, the six images do not show, and there is no active link. Viewing the page source indicates that there is no img tag for any of the images.
If I view with Konqueror on my linux system, the images are there and the img tags exist in the page source.
So obviously the webserver is providing the html code correctly and something on my XP system is altering the code.
Two other people have checked this out. The owner of the site can see the images on XP and also on Mac, and someone else can't see the images on XP

I do not have Norton Antivirus, but I have heard of similar problems that disappear when Norton is disabled.
I do have Zonealarm and eInoculate, but have heard nothing about these apps rewriting html code.

Does anyone have any idea what might be going on?

I see the images and I am running XP and Firefox through a firewall with anti-virus. I have never heard of code being rewritten on the fly...

Well the code is definitely different when viewed from my XP from what appears when viewed from my linux box.

<table width="648" border="0" align="center" cellpadding="0" cellspacing="10">
<tr>
<td width="216"><a href="arcs.htm" target="_blank">
</a></td>
<td width="216"><a href="artsy.htm" target="_blank"> </a></td>
<td width="216"><a href="autumn.htm" target="_blank"> </a></td>
</tr>
<tr>
<td align="center">Arcs</td>
<td align="center">Artsy</td>
<td align="center">Autumn</td>
</tr>
</table>

You will notice that the img tags are missing. If you look at the source code from your browser I am sure that the img tags will be there. So something appears top be rewriting the html code and it is not the server. And it is unlikely to be the browser, as different browsers on the same machine are producing the same result.

I believe what you're saying...and when I view source I do see all your code. I have been all over Google looking for something similar with no luck yet. Hopefully someone else has seen this...very trippy.

I have heard of NortonAV or firewall ignoring 120x120 images on the assumption that they are ads http://jalbum.net/forum/thread.jspa?forumID=24&threadID=6594&messageID=54414#54414
But that doesn't apply here as I don't use Norton (and the images are not 120x120!)

AHA!!!!
The problem is with ZoneAlarm!

Here's how to fix it (from ZoneAlarm help)

Setting ad void control options
When Zone Labs security software blocks banner, skyscraper, or animated ads, it leaves a "void" or blank on your screen where the ad was to be displayed. Ad void control lets you specify what will be displayed in that space.

To specify what appears in place of blocked ads:

Select Privacy|Main.
In the Ad Blocking area, click Custom.
The Custom Privacy settings dialog appears.

In the Ad Void Control area, specify the method for controlling blocked ads.
1 Nothing Blocks ads without any indication that the ads were to appear.
2 A box with the word "[AD]" Displays a window containing the word AD. This is the default setting.
3 A box I can mouse over to get the ad to appear Displays a window containing the ad that appears only when you activate the window using your mouse.

Click OK.

I used setting 3. Now a grey box appears instead of the image, and when I mouse over it the image is restored.
It seems to me that ZoneAlarm should default to option 2 or 3, particularly if the ad detection is so prone to false positives.
