Read plenty here about embeding, however most seems to lean towards using iframes. Not really that good.
I have an external dynamic page (specifically an amazon shop) that I want to call inside my blog.
I thought making a page with wp may work so that I keep the same look and feel however I can not get it to center correctly with an iframe and I still have the right hand colum in the blog there that is not needed.
I installed Gallery the other day and it fit seamlessly by creating the separate header and footer for the gallery. Looks great.
