Download binaries

The latest binary executables are available under
https://bintray.com/suntong/bin/web2image#files/web2image
as the result of the Continuous-Integration process.

I.e., they are built right from the source code during every git commit automatically by travis-ci.

Pick & choose the binary executable that suits your OS and its architecture. E.g., for Linux, it would most probably be the -linux-amd64 file. If your OS and its architecture is not available in the download list, please let me know and I'll add it.

Installation

To install the source code instead:

go get github.com/suntong/web2image
