Is It Ok To Resize Images Manually Without Updating Resolution In Db?

I'd like to mass downsize images on the server using shell scipt.


find ./images -type f -size +1M -exec mogrify -resize "2048>" -quality 88 {} \;

However I noticed that in cscart_images there's a resolution next to each image. What downsides could it cause if I changed the resolution behind the scenes leaving higher resolution in db?
