图片上传插件
An extension that handles file uploads intelligently for your forum. This is the descendant of the Flagrow image upload extension.
功能：
- For images:
- Auto watermarks.
- Auto resizing.
- Whitelisting mime types.
- Uploading on different storage services (local, imgur, AWS S3 for instance).
- Drag and drop uploads.
- Uploading multiple files at once (button and drag and drop both support this).
- Easily extendable, the extension heavily relies on Events.
