LinkBrowserWindowHeight

This option sets the height of the built-in resource browser used in the "Link" window. By default the height is expressed in percentage of the screen. E.g. 0.7 equals 70% of the screen.

FCKConfig.LinkBrowserWindowHeight = FCKConfig.ScreenHeight * 0.7 ;

Of course you may also express the width in pixels. Example:

FCKConfig.LinkBrowserWindowHeight = '220' ;
