For Google Drive I can deeply recommend paying once for https://www.insynchq.com/ using it myself for years and have not touched the official client for years (and I'm on macOS).

About IrfanView: I've found nomacs to be a good Linux native replacement.

You've never used rclone? Rclone is the bomb..

I have, and i also bought a license of Overgrive, a good program. But both still arent as easy/set-and-forget as Google's main client in Mac.

Ha, I even moderated a german IrfanView forum back in the day until I switched to Faststone Viewer. Almost forgot.

Oh wow. That name brought back memories.

Have you tried XnView?
