I’m having the same issue as described in this topic: I have a PNG image that I need to appear smaller (it’s a logo basically), but when I reduce its width it loses quality and appear as if is was a low res image.
We can only see the screenshot, not the app, so it is better if the resolutions match. It would be even better if you can deploy a public app in streamlit cloud showing the issue.
In the first case, an scaled-down version of the image is served from the application itself. The second image is served as is from github and the scaling is left to the browser.
