Yeah, you're correct. Any formulas in Quick Base will only change the displayed size. To actually change the size of the image, you may need to use a service like Kraken.io or something similar. Fortunately, they have APIs for scaling as well as for orientation. I've not used the service, so I can't speak for their reliability or ease of integration, but it looks pretty straightforward.
