How to upload image to field in a row in a collection?

Hi, thanks for the awesome work on this.

This works: `rows[0].set_property("screenshot", "https://neurosphere.io/images/Produkt_komplett.png")`

But how can I upload an image from my local files directly to this field?

The issue only identifies rows[0].set_property("screenshot", ...) and does not name a source file or test. Start by tracing how notion-py handles collection row properties and remote file references, then determine the client-side upload entry point. Done means a local image can be attached to that field and the resulting value is usable in Notion.
