Batch AI Framed Paintings

I have 100 individual paintings and 8 pre-made template images, each with a different-coloured frame. I need every painting placed into every frame, producing 800 finished JPEGs.

Here’s what I’m after:
• A fast, repeatable way to swap each painting into the template (the Nano banana model is the text-to-image AI I currently use, but I’m open to anything faster or higher quality).
• Consistent output: full-size JPEGs, identical resolution and aspect ratio to the templates, clean edges with no artefacts.
• A clear folder or naming convention so I can instantly see which painting sits in which frame colour.
• Turnaround within three days of project start.

How you get there is up to you. If you prefer manual prompting, great—just keep it quick. If you can code a small Python script or use an automated workflow to batch all 800 swaps, even better; please include that script so I can rerun it later.

Let me know your proposed method, the tools you’ll rely on, and anything you need from me (source paintings, template files, prompt style, etc.). I’ll supply all assets immediately on award and will be available for rapid feedback.
