How to change icon size in iWorks media viewer

Hi

I have just upgraded my wife's macbook from 10.6.8 to 10.8.2 and she uses pages a lot

The media viewer in pages seems to have just one size for the icons of the photos. You used to be able to drage a slider to increase the size

I have tried all the ctrl key type ideas but nothing

Why do they delete features that are d=so useful or hide them in non obvious palecs and make it hard for the less technical user.

I have been using pages since the first and a Apple since 1980 and support 500 machines - most using pages so I would appreciate any help.

Mountain Lion has made Pages a little less friendly

Yours
