Hello Thomas,

>> I have been playing with the code and still struggling a bit, the increase of image size does work however it shrinks the title and price

Yes, you right. it happens because you increase size for photo but decrease for right box of photo.

>> is there any way t move the seller information and google map down so the information of title in the middle is not squashed? something like this

yes, it is possible but it will take a lot of time(it will be small customization).
I suggest you submit ticket and our staffs will help you.

Thanks.
