## Description
### Issue:
Non-animated webp / gif files were using `metadata.pages` to calculate
it's resized heights for `imageSizes` or `cropping`.
### Fix:
It should only use this to calculate it's height if the file's
`metadata` contains `metadata.pages`. Non-animated webps and gifs would
not have this.
