Although I've no idea how Symantecs filters work, I do now that this
size of images are blocked by my user stylesheet. Those 88 by 31
images fall in the category of small ads unfortunately. I had the same
problem with some logos a client wanted to include.

A simple workaround for those problems would be to change the image
size slightly (89 by 31 px would escape out of most filters).
