Productpage 1a seems to me suitable, with 1 product to see or the standard productpage, but for using the standard productpage it is necessary to remove the positon of the button to fit the two productpics.
To chance the default productpaylayout i must something know from the "tokens" used and understand the structure of how the productpage is built up
For selling carparts i don't like the small thumbnail pics: those racy customers like to see their custom products here in Europe and why not?
( if you take the example site of K-motorsports than it is too small the pics)
Agora seems to be have no problem via picserve to show those large productspics
Therefore sometimes therefore there must be a extra(1 or 2) productpic and text to explain the product in greater detail
( it is easy to make a digital pic these day!)
Replacement of the default productpage that's the trick
thanks!
