editable regions

Hi guys,

How do i place editable regions in a publishing page layout?

As an example i'd like to have a table with 2 rows and 2 columns as simple as this,

with all those 4 regions editable, where somebody can update the picture and picture descritpion:

Picture A	Picture B
pic. A description	pic. B description

I have read this article: http://office.microsoft.com/en-us/sharepointdesigner/HA101741281033.aspx

but i'm still stuck...
