Dia Show -> Default Picture Size

Hi Community,

where can I adjusted the default dia show picture size. There is a pulldown menue with 320x320px as default value an I would like to adjusted this value to 1024x1024px as default. I'm using the carbon theme and I know the dia show configuration help file >>http://svn.sourceforge.net/viewvc/gallery/trunk/gallery_remote/defaults.properties<< but can't find an entry about the default picture size...

Can anybody help?

Thx in advance Pronto
