Media in Iweb/Iwork/Mac in general

Hey guys and girls

I recently updated the software on my mac and a lot of things have changed, some good, some bad.

The bad thing, which i need to fix soon as it saves hours of my time, is the Media selections throughout my mac.

What i mean by this is, when i go into e.g. IWEB, i can usually go into the media tab and find my whole itunes library, playlists and everything, plus i can usually find my iphoto library, Albums and everything, i can do this now.

Another e.g. would be when you change your desktop picture, my iphoto library is no longer there.

Does someone know how i can get this working again

Much respect for whoever can help

Cheers
