i refuse to waste my slow internet connection on loading adverts - i suggest you do the same!
Instead of using explorer etc try downloading Mozilla Firefox, to this you can load add-ons (selected from the mozilla homepage) one of the most helpful being Adblock Plus. This allows you to load a profile of typical ad pics to be banned from being displayed - one very very rarely does pop up (happened twice in the last year) but you can simply all it to you profile of banned items... brilliant stuff and makes the pages load faster if you don't have a super fast broadband
