No I haven't contacted Symantec about this, and I don't think I will either.

As I said in my second e-mail about this, the ad blocker seem to strip all
images with width and height attributes set to 31 and 88 (I assume this is a
standard dimension for ads), but I circumvent it by using a style rule for
this instead (or I could just drop the width and height attributes
altogether). Later on I noticed the same thing at several other sites, in my
search for "powered by" logos.

I just wanted to inform you about this bug since I thought you were affected
by it, but I see now that this ad blocker must do so in error for a lot of
sites. I'll leave it at this.

Best Regards,

  Peter Albertsson

The "valid" icons aren't ads, so if this tool removes them as such, 
it's broken, and unfortunately there's little we can do about it. Have 
you contacted this tool's vendor about this bug?

Thank you,
