Album art questions

Hi, is there anyway to have musicbrainz download the album art from the original release or the first release. I would really prefer to have original vinyl art from first releases even if they are japanese remasters etc.

Also, if I drag and drop my own image file onto a release for the art and I have the setting checked to write images into the tags. Will it still write the image I dropped onto the tags? And if so can I then delete the image file?
