김영한님 답변을 참조하여 코드를 작성해보았습니다.

v1. png 이미지 전용

@ResponseBody
@GetMapping(value = "/images/{filename}", produces = MediaType.IMAGE_PNG_VALUE)
public Resource downloadImageV1(@PathVariable String filename) throws MalformedURLException {
    return new UrlResource("file:" + fileStore.getFullPath(filename));
}

v2. 모든 Content-Type 사용

@GetMapping("/images/{filename}")
public ResponseEntity<Resource> downloadImageV2(@PathVariable String filename) throws IOException {
    String fullPath = fileStore.getFullPath(filename);
    MediaType mediaType = MediaType.parseMediaType(Files.probeContentType(Paths.get(fullPath)));
    UrlResource resource = new UrlResource("file:" + fullPath);
    return ResponseEntity.ok()
            .header(HttpHeaders.CONTENT_TYPE, mediaType.toString())
            .body(resource);
}
