Automatic Uploading and Display of Images (ELI5)

Hi. I'm totally new to Squarespace, a backend programmer thrust into this role by company needs.

In brief:

• Our company has a website on Squarespace.
• I have a process on a remote server that periodically creates new images.
• I want to upload those images automatically (sftp or some other secure service) to the company website, over-writing any old images, and have the web page display the latest.
• I have no clue where to start.

How do I upload files? Where do they live, once uploaded? How do I get the Squarespace block to pick up the latest image? I'm used to a Linux command prompt, so everything is opaque here...

Can you point me to documentation, suggestions, or something to get me started?

Thanks.

This isn't possible on Squarespace.

It's a serverless environment with no SFTP access (or similar) for image upload.

To display them on Squarespace you would need to manually add them each time (drag and drop process) or place them on a [non-Squarespace] server from where they can be served via an iframe. 

Thanks for the reply. Oh dear.
Hmm. Back to the drawing board(room).
