Sense Theme - I want to add a picture using custom liquid code in the footer, since it does not have option to add an image

I want to add an image below the footer subsection in the footer section, but that option is not available in the theme. I have uploaded the pic to my files, but I am unable to find ‘Add New Asset’ under my code. I tried using the following code:

<img src="{{ 'your_image_name.jpg' | file_img_url: '1024x1024' }}" alt="description of image" style="max-width: 100%; height: auto;">

But when I paste the URL for the image - https://cdn.shopify.com/s/files/1/0797/0645/6293/files/Proud_Member_of_Tea_Guild_of_Canada.png?v=1771734765

it gives me an error.

Use Shopify Sidekick :+1:

This need to be either

<img 
  src="{{ 'Proud_Member_of_Tea_Guild_of_Canada.png' | file_img_url: '1024x1024' }}" 
  alt="description of image" 
  style="max-width: 100%; height: auto;"
>

or

<img 
  src="https://cdn.shopify.com/s/files/1/0797/0645/6293/files/Proud_Member_of_Tea_Guild_of_Canada.png?v=1771734765" 
  alt="description of image" 
  style="max-width: 100%; height: auto;"
