How can I parallelize image printing

Hello everybody,

I have a series of data files that I would like to plot and save as png files. There is no need to print to the screen since all I'm interested is the png files. Is there someway to parallize this? I've tried parfor but it gives me errors and terminates my connection to the other labs (I'm running this on my desktop not on a server). Any ideas?

Thank you very much for the help,

Elad
