Improve the performance of Reviewing a photo.
fix: 5144370
There is two componenet in the photo page. One is the large photo and the
other is the thumbnail strip. They idenpendently load their own data and images.
This change fixes several issues here:
1. Prevent sending to many jobs to ThreadPool and block others.
In a worse case, if the thumbnail strip send image requests first,
it may block the ThreadPool very long.
2. Improve the performance of extracting thumbnails from local files.
Now we try to extract the thumbnails from EXIF data first.
