 FastImage finds the dimensions or filetype of a remote image file given its uri by fetching as little as needed, based on the excellent [Ruby implementation by Stephen Sykes](https://github.com/sdsykes/fastimage).

+1. Support BMP,GIF,JPG/JPEG,PNG
+
+###Ver 0.2 By Chen.Zhidong
+1. Enable WEBP type image
+2. Add timeout and refer to fopen to avoid time waste and blocked by Hotlink Protection
