Thanks Mike and Roger - seems like it works on OSX at least despite the notes in the docs:

I'm keeping the technique below as it allows me to reposition the image within the oval by dragging it around - but then when I want to keep it I will export the snapshot and then set the backgroundpattern of the graphic. By the way I can't get the new syntax to work: 1. > > New variants of the import snapshot and export snapshot commands have > been added: import snapshot ... at size width, height > export snapshot ... at size width, height > The script editor does not like the syntax?
