...I have come accross norton blocking banners and images that could be some way associated by name, folder or content to be banners but the images it is blocking all have either obscure or normal names, contact.jpg, dugandjon.jpg etc.
My thoughts on the subject are;
A. One of the images has hotspots to email staff.
B. One of the images has an alt message with telephone number.
C.It has been suggested that image size is a factor but images are just 250x250 or 300x300 which are fairly standard and surely this is a stupid way of blocking ads as most sites set their stockpix to similar sizes.
Has anyone else come across this issue?
Has anyone got solutions to this problem, the only thing I can find on Symantec suggests changing settings in NIS which isn't a solution as you cannot get anyone who visits the site to change thier NIS settings.
Change your images to "odd sizes" ie; 163 x 123 and this ought to work ..because yes ..this is a stupid way to block ..and that one of the ways that N****n do it ..
See: [webmasterworld.com...] message #3 for a list of "banned" directory names and dimensions - however, the list can change with subsequent versions of NIS.
NIS is considered evil by many here because of its heavy-handed and deficient approach to ad-blocking. This search [google.com] will point you to a few thousand more posts on the subject!
Basic rule is to use meaningless directory names for graphics, and to try to avoid standard ad sizes - for example, without even changing the image file, if you specify that a 300x250 image is actually 301x250, you will see no difference in the graphic, but NIS won't block it.
I was browsing our portfolio of sites today on a system that had NIS installed. At first, I could not figure out why certain images and/or links were not appearing. When I viewed source, there was additional javascript at top and bottom and those areas that I could not see were vacant of content.
After a little digging I come to find out that NIS is responsible for this. Yes, I was using a directory path with one of thousands of words being blocked by NIS.
I then decided to check other image based advertising campaigns and found that CSS has come to our rescue in certain instances. Since we are specifying image sizes via CSS (later designs), NIS cannot see the standard IAB ad sizing, snicker, snicker, snicker... And, we used terms in the URI path that do not appear in the megalist published in another WebmasterWorld thread.

That's a good workaround. Thanks for bumping that up.
The use of iFrames was working for a while, but a few months ago, Norton got smarter with allowing them to partially load and then blocking parts of the frame depending on what files are being called.
