We have IE 6, and on some web pages that we go to, we can't see the pictures (example, ebay). I don't know if the pictures are jpg are gif, but instead of the pictures we see a big square, and on the upper left corner a small square with an X inside.
Right clicking on the picture opens up a menu that gives me the option to "Show Picture". I choose that but nothing happens besides a quick change in the X, that becoems an X again.
In IE settings, the show pictures is checked.
We have a SonicWall 230. In don't see anywhere where we could be blocking these pictures.
