The FileSize field it returns is the size of the file on disk. If you want to know the size of the uncompressed JPEG image you can multiply Width times Height times BitDepth and divide by 8

Yes. When it's on disk, it's compressed. It only gets decompressed after you call imread() which reads it from disk, uncompresses it, and places it into the variable you specified.
