Description

Context: https://tour.golang.org/moretypes/15

Running the slices exercise doesn't display bluescale image. Instead it displays the slices of slices returned by Pic and as the last line prints "IMAGE: ".

Contributor guide

Research direction
Investigate the Go tour's source code to understand how pic.Show renders images and where the debug print output interferes. Look at the file x/website/ content/tour/solutions/slices.go and the handler that serves the tour page.
