I'm not sure if this is a Safari / .Mac feature, but it is different from the way other browsers work with .Mac.
When you visit a homepage on .Mac that has a set of photos you have the option to view a slideshow of the images. This is the same for all browsers, and it opens in a new window. The way photos are displayed though is different.
In IE and Mozilla they get drawn from the top down as all graphics seem to be in browser windows, as though the file is being loaded and it fills in the blank screen from top to bottom.
In Safari it does not do this, it seems to load all of the photo before it starts to show it, and then it slides it down from the top of the screen, just like a transistion effect in a real slideshow.
it's very neat and much better than the standard method of building graphics up as they are loaded.
You can see it if you look at my homepage :-

Try the Disneyland Paris ot the New York photos.
Do you think we will discover more features like this between .Mac and Safari as they are developed?
