For several years now I have not sent out any sponsor photos. Instead I've been making calendars using iPhoto, and purchasing them through the Apple Store. They're a little pricey at $19.99 each plus tax & shipping, but I've not found another print source that's less expensive, but yet has the quality found in these calendars.
My thought process behind this, is that I see photos hanging on the walls of business, that are quite outdated and covered with dust. With a calendar, you can present your sponsor with 12 different photos, all of a quality to frame if they choose. If they don't choose to keep them, they can toss the calendar at the end of the year without guilt, because next year they'll have 12 new photos to look at.
