image_viewer usage

[Valmor de Almeida]

Hello,

I would like to use display as my image viewer to display a scaled 
version of a large image:

display -resize 10%   imagefile.png

This command does not work:

  image_viewer("display -resize 10%  %s");

and I am not sure about the image_viewer() syntax. Could someone help?

Thanks,
