I need 20 small images put into one image

I need an experienced image editor to update an AI-generated banner showing 20 framed paintings on a wall. The AI has altered the artwork, so I will provide the original images to place inside each frame. Please replace the paintings with the matching originals while preserving the banner’s layout, frames, wall, perspective, lighting, and overall style. The finished image should look natural and seamless, with every picture clear and correctly positioned. Please deliver a high-resolution final file suitable for online use.
