How can I embed an image within the exe file

[swagar]

How can I embed an image file within the exe file as a resource like the manifest. At the moment I need to put the original image file along with the exe file and this is a problem since the program doesn't run without the image file.

I had the same problem with the notifyicon example.

with version 1.16 we can simply insert the icon into the *.exe

	if err := ni.ShowInfo("Walk NotifyIcon Example", "Click the icon to show again."); err != nil {

	// Run the message loop.
	mw.Run()
}

I hope it helps

Because of the "image" can't parse .ico file. Just use this package:

go get github.com/mat/besticon/ico
