Set axes=FALSE in image(). In this case - as in many others - running 
example() - here example(image) - on the function does point in the right 
direction. The function help files, and especially their examples, are 
places where much wisdom is to be found!

source() the file. On Windows, there is a menu item "Source R code" under
"File", but sourcing from the command line lets you change arguments. On
Windows you may find source(file.choose(), echo=TRUE) useful - but perhaps
turn off buffered output in the "Misc" menu first - otherwise the console
stays blank until the whole sourced file is completed. On other systems
console output is not usually buffered.
