I have been having some problems with the photo hosting website http://www.pbase.com/ and Zonealarm's 'Ad Blocking' filtering out the HTML for some sizes of the images.
I tried to give some example HTML but it looks like this forum won't allow that, however the pbase forum will show it:
With 'Ad Blocking' set to 'high' it seems that Zonealarm thinks that the pbase image is an advert, even though from the size (either greater than 800 pixels wide or high) it should be obvious that it is not a simple banner ad.
