Hi @teolemon!

I've opened this PR to address issue #55 — documenting the image addition feature in the Python SDK.

Here's a summary of what I've changed:

• Added a new ### Add an image to a product section in docs/usage.md with usage examples, supported image fields, language suffixes, and image requirements.
• Updated README.md to include add_image in the description and examples section.

Since you originally opened issue #55, could you please review the changes and let me know if anything needs to be corrected or improved? I want to make sure everything accurately reflects the actual API behavior.

Thank you!
