is once created permanent and changing it (especially in uploaders) is probably a bad idea!
* `:tempfile` - path to the temporary file. Prefer in-place changes on the file rather than changing the
path as the temporary file is also tracked by `Plug.Upload{}` and automatically deleted once the request is over.
+ * `:width` - width of the media in pixels
+ * `:height` - height of the media in pixels
