Need different widget for each post – Possible?

Hey guys,

Just a quickie. I am starting a review site and on each post I would like a picture of the product on the sidebar with a link to where to buy it from. Obviously for every product, this will be different so I need a different widget on my sidebar for each post I make (Which will go into the hundreds…it’s going to be a big site).

Is this possible? Or are there any ways around it? Thanks ??
