No, add the print command on the Image elements at the point where you want the corresponding Image element to be printed, ie. on where you used to have your newImage commands (they would be printed there too because you used to have print on defaultImage)
The error messages you see are telling me that you’ve added the four newImage commands below newCanvas in addition to the newImage commands you already have below in your script, thus resulting in two copies with the same name of each Image element. You should not create and, importantly, not print the Image elements at the beginning of the trial: you want to print them at different time points during the trial, so the print commands should go on the newImage commands that already are further down in your script
