Norton Ad Blocking

[u2ill]

After a few hours of pulling hair out, I've finally discovered why some images are not appearing on my pages. Appearently, if Norton Ad Blocking is enabled, Norton strips out any <IMG> tags that are serving images from directories named 'ads', 'adverts', etc...

It seems kinda messed up to me that I have to change the names of directories on my website because of firewall software that everyone uses.

My question is: Does anyone have a list of all the directories that Norton's watches for? I couldn't find one on their website (not like they would publically announce ways for webmasters to get past their evil ad protection system).

I believe that's a customer option that can be turned on or off depending on whether a customer wants to see images. I know many people that use that feature when they are on dial up to help pages load faster. I think the firewall looks for images no matter what directory they are in... example. .jpg, .gif etc.

I take that back. All the Ad Blocking patterns are in Norton's "default" list for Ad Blocking.

But still, the whole premise of stripping out the entire <IMG> tag when the browser loads the file disturbs me. The ads I'm displaying are sized so as to make the page display correctly (they are in a table). Now I need to add code to size the table itself instead of letting the ads size the table.

God how annoying!

They are stripped if one of two conditions is met:

1) If they contain a banned string (i.e. ad, advert, banner, afiliate etc..)
2) If they of a standard banner size

So, avoid using URLs that look like advertising and avoid using sizes that are standard sizing - just one pixel bigger or smaller can make a huge difference.

If you think that's annoying, their popup blocker injects JavaScript code into any page that has JavaScript in it, and that breaks some pages that don't even have popups.
