How to remove the image block between the product information and the header

Site URL: http://orca-trout-3ltl.squarespace.com

Hi - I've been reading forums and trying to input various codes to help this issue but so far no luck.

There is blank space between the product information and the header on my page and when I click on design/image blocks I am able to see that there is actually a block there creating the space, but so far i've found no way of removing it.

I've attached a screenshot of the space that I mean, with the block in question highlighted. I am on a demo account at the moment and am using the Ventura template for reference.

Any help at all would be greatly appreciated, thanks!
