[ic] How to make a "next product" link in the flypage

[Thomas N. Stefanidis]

Hello,
When someone is seeing a product,how can i make a "next product" link
that takes him to the next product in that category?
Let's say i have the category "shoes" and i have 5 shoes in it.
If he chooses the "shoes number 2" i want a link to take him to "shoes
number 3"...How about a "previous product".

Thank you.

Thomas
