Websites PNG32

Narnia Site

The Narnia Website uses several PNG32 images; the PNG32 images are identifiable by their transparent backgrounds.
These include the characters and objects i.e. menus.
When the site loads these images come onto the screen over the background separately indicating multiple PNG32 files.
The background could also have been done using PNG format however it would more likely be PNG24.

Seek the Signs .com and .co.uk

The Seeker site also uses PNG32 files this is more visible in the .co.uk version.
PNG32 files on the Seeker site include the celtic symbol on the menu of both the .com and .co.uk site as well as the menu/description to the right of the screen on the .co.uk site.
Both sites include visual feedback.
On the Seeker site this is used in combination with the PNG32 celtic menu at the bottom which responds by expanding on the over state.
This could have been created by creating a button and then altering the over state of the object to a movie clip.
Other visual feedback includes the highlighting of objects in the over state this could have been done in a similar way to the celtic menu but altering the background and text colours.
There are also multiple seperate movie files.
