thank you for your reply. where might a newbie learn these 
incantatory-loik commands?

sadly, however, pasting these suggestions produces a console screen's 
worth of activity, [1] and several new listings. but no imagemagick 
listing in any of the menu pull-downs. i checked them all, although i 
would expect imagemagick, for instance, to show up on the graphic 
pull-down. synaptic package manager v. definitely says imagemagick's 
"installed"???
