Need custom code to be able to add a banner image to regular Shopify Pages

Hi,

I'm currently working on my store through Shopify. I'm using a Premium template named Seasons from Barrel NY. What I need is to be able to add banner images similar to the Collection Pages within the Seasons theme to regular Shopify Pages (FAQ, About Us, etc.) I emailed support at Barrel NY and they replied saying that Shopify does not have a built-in feature for that and that they do not support custom code for that.

What I would like is the code that I can place in the Pages HTML so that I can load banner images for those pages. I've attached a page from the Handbag Collection that features a banner image and a regular page that does not have a banner image.

Let me know what else you may need. I look forward to hearing from you.
