-## Comparision to `hexo-asset-image`
-
-At first when I wrote this plugin, the older `hexo-asset-image` has been inactive for quite a long while.
-
- Up to now, there is still a lot of issues remaining open. And I smell of hardcode (no offence), which may lead to more and more problems.
-
-In the end, all of these trouble comes from upstream Hexo, I'll keep an eye on it. This plugin's maintenance will last until I deprecate Hexo, which would a long time later, no need to worry.
