Butterfly Viewer can view multiple images side by side with synchronized panning and zooming. Simply drag and drop image files into it and it'll auto-arrange them as a grid, column, or row.

I'm the creator, and I recently released it to the public on GitHub.

You can install it on Windows, run it as a package for MacOS (beta), or run it directly on its Python source code.
