We'd like to be able to prevent images from being upscaled by Resolutions, for them to only be downscaled when appropriate, and otherwise to be left alone.
![upscaled.png upscaled.png](/t5/image/serverpage/image-id/4253iF11FEECB1E348298/image-size/large?v=v2&px=999)
So, in this mockup, with the "Upscale smaller images" option unticked, if an image is 700px wide it will be downscaled to 600px, but if it's 500px wide it will be left as it is, it'll be up to us to provide an image with larger dimensions.
If the "Upscale smaller images" option is ticked, the current FirstSpirit behaviour would occur, where the 500px wide image is upscaled to 600px.
If this is already possible, please let me know.
