Visual treasure hunt

I went to Waveland, Mississippi a couple weeks ago to re-photograph Hurricane Katrina scenes for this video story, and took some 8x10 prints along to help line things up (like clues in a treasure hunt, the prize being views of interesting change). In this case, the print matched, and on a whim I shot this picture using ShakeItPhoto, an iPhone app that mimics a Polaroid camera. I hadn't thought to publish it until a fellow editor suggested we ask your opinion: is it worthwhile to publish cell phone pictures? Does it matter if they've been altered by an imaging app?
