Disappearing code in webpage

Code not displaying

[Interent Yogi]

Hi all I have a situation that has been bugging me for a couple of years actually with one page on one site and I was hoping for a explaination.

Now It was happening on 3. Am I going nuts?

I am running windows xp home .

I have a page where my browser is deleting a selected line of code.

When I preview on my hard drive in IE the page is fine I see the image as per the code below .
</tr>
<tr>
<td width="320" height="250" rowspan="2" align="center" class="subHeader">
<img src="images/mm_imagegrass.jpg" alt="puregreen" width="250" height="250" class="image"> </td>
<td width="30" rowspan="2">&nbsp;</td>
<td width="260" class="subHeader">A combination of life greens <br>
<br> </td>

But when the page goes online the image disappears.

When I view the source in the broswer tried 3 browsers, This line of code has gone . ( I do a track changes in word for the offline and online version and it is crossed out )

<img src="images/mm_imagegrass.jpg" alt="puregreen" width="250" height="250" class="image">

If I look on other computer the image appears and in the file manger of the hosting the code is there.

The Question is why has this specific image /html code not displaying when it is online and only on this system. I have tried the 3 major browsers and no luck.

The other site, there are 20 images on the page and I cannot see 3 of them .

Any ideas appreciated .

Try doing a Ctrl-Refresh.

What code is in the class="image"?

[DrDoc]

This line of code has gone

That has nothing to do with CSS. Either the page is cached in the browser (or by proxy) and thus not appearing (hence the need for Ctrl-Refresh) ... or else the page has not been uploaded properly.

It will probably be because of Norton Internet Security, as the image is 250x250 which is an image size blocked by default by the Norton ad-blocking component. See message 3 in this thread:

[webmasterworld.com...]

Switch the dimensions to 251x250 and the problem will go away - there will be no noticeable difference in the image rendering.

Does Norton Internet Security physically remove the code from webpages?

[tedster]

Yes, I believe Norton does remove code from the local version of the source.

Thanks everyone for their input . I have been here since 2002 so I know about the CTRL refresh thing and I checked code 10 times to make sure the FTP went fine.

Encyclo AWESOME ...I feel 100 kg lighter, I changed the image to 251 px and BINGO it is now there. As for the other site, it has images where the names happen to be admaster pens and the link codes actually disappears also. So it pays to keep these things in mind when designing a site I guess. The link to the other thread explains it all. It was what I suspected
Norton Interent Security and it does Strip/ Delete the code out of right out the HTML . Even when it is disabled Which got me, as that was one of the first things that I tried.
