I see. Then maybe it's not a bad idea to create a new option in the Unclog menu so that Qimage will print not a color pattern but a pile of photos one at a time. This way it'll be more useful.
That's probably going to cause more problems than it solves. It prints a purge sheet because that is effective at keeping nozzles exercised so for the purpose of exercising the nozzles, there is no substitute for the unclog pattern. Printing a batch of "random" photos over time (say one a day) could lead to problems because it won't exercise the nozzles the way it should, some colors may not be accounted for (or not enough) and using it that way could give you a false sense of security thinking you are doing proper exercising of the nozzles when you are not.
