Simple to use plugin

Hi, I have created a wordpress web site for my 15yr old son to sell his photos as a fundraising venture. We are using WordPress 4.0 running Hum theme. We have the Woo Commerce plugin, but my son finds it is too time-consuming to keep updating with more photos. Is there a plugin available where he can set standard prices (e.g. digital copy $15, A4 glossy print $20, A4 canvas $25 etc) and apply them to all the photos? Or can this be set up somehow (easily) in what we already have? Any polite suggestions and/or help would be most welcome.
His website is http://www.churphotography.com
