Is PictureMarkerSymbol auto-re-sizable?

[EricJing]

I am wondering, is it possible to make PictureMarkerSymbol auto-re-sizable while zooming in/out?

You can set ReferenceScale on Map and publish a feature layer using a PictureMarkerSymbol with ScaleSymbols=true. Reference scale should work for picture marker symbols. It's quite likely that the picture image will not look great as you zoom in and it gets larger. 

Please refer to the links for more info :

Map.ReferenceScale Property and sample Map reference scale | ArcGIS for Developers
