oscommerce problems

Hi All

I am currently trying to create an ecommerce website and am using oscommerce. I am haveing some problems in a few areas though.

Firstly i have removed the US currency and replaced it with the Australian currency (as this will be an australian only site). That went easy enough however now all of the products i put into the site display 0 as their price.

Secondly i would like to move the specials box from the left column and put it into the box in the middle of the screen, it is called something like new products for 'month'. i dont know the exact name of the box. so if anyone could tell me it would be good. And im also wondering if i just copy the contents of the specials box to the new products for 'month' box will this work? i need the specials to be displayed along the bottom middle of the screen.

Thirdly when i view the site in a browser on another computer (not development) i can get the main page only and none of the pictures show up. i can browse through any links view any pictures or basically do anything. I am running Apache2, php4 on windows xp pro.

Any help will be apreciated!!!!

Regards
Gavin
