Is there a better way to check if images are the same? I now use imagedata

My basic suggestion is that you use the location data of each connected dot, rather than the image data.

Seems you could just loop through each dot in the reference path, then see if the same dots are included in the user’s path. You would need to include a name for each reference point, of course. That’s if I understand your problem correctly.
