For the context of this app and in general, I would agree.

While I was at PyCon, I had prepped a version of my resume that had my photo on it, and during the job fair I shared them with folks and companies that interested me.

I figured, if there's any chance of someone remembering a person and wanted to recommend them, a photo would go well with the name and info. But maybe it was ineffective :) I didn't think it would hurt to include, at the very least.
