what`s the ratio bandwidth / traffic
 

I`m setting up a tgp site, and see all kinds off different bandwidth choices. But how do i know how much i will be needing.

Let`s say a have 15K traffic a day.....howmuch bandwidth will that be spanding???

It all depends on the size of your site. On mine 15k traffic is about 1 gig bandwidth, but I'm using those annoying thumbnail-links to galleries.

Exactly so. Add up the size of all the graphics,banners,thumbs,etc ..
Add onto that the size of your htm page and any js files .
Multiply that total by the amount of traffic and you have your bandwidth.
