In my former capacity as a church technical director, one of my jobs was to coordinate publications for inter-church events that we hosted. I'd receive promotional material from a variety of sources and be tasked with helping to produce event signage and advertising. I would often receive materials in a wide variety of formats and have to convert it to something useable.

Of course, sometimes what I received was just plain useless. A 95px X 100px compressed jpeg portrait of a preacher just isn't very useful for printing posters, no matter what the secretaries think. "Yes, it looks great on their website, but it won't work for the posters. See if they'll send you the original."
