This may be answerable with a general Tk knowledge (newbie here), or may be a module-related prob., but having issues with my script (the following is a pared down version -- note: To get the following script functioning, it needs to run in a folder with 'England' and 'Scotland' subfolders, each containing 'pic1.jpg' and 'pic2.jpg.)
My problem is that, when you select either England or scotland from the radiobutton, the Thumbnail is redrawn below the previous (rather than refreshing the contents of the thumbnails). I have tried $thumb->configure(-images=>[<@selection>]), but that came up all errors. Is there a workaround to, e.g., kill the Thumbnail instance, or perhaps refresh / empty the contents of the mainframe?

Any help/advice appreciated.
