Avoid Image Downscaling?

I’m trying to make an image database app. I know that appsheet automatically downscales pictures to 600px wide, even if they are stored as a URL value. I’m wondering if there is a way around this?

Through playing around, I noticed that if I drop some random image URLs I find on google images, the images actually stay the original size. For example, If I put this URL as the app formula into an image type column, the image maintains full resolution (seen in the screen shots regular view and zoomed in view). But if I put in a URL like this that I have stored on our servers then appsheet downscales it to 600px wide.

What’s going on here? I’m assuming it must have something to do with the way the images are stored? Any tips on how to avoid downscaling?

Don’t know why the first hotlink isn’t working, here’s the URL:
