People like to see pictures of people. Use less words to make your point and include a few interesting shots. I have visited plenty of missionary web sites that have absolutely no photographs. The one's with interesting, fast loading, pictures usually will hold someone's attention longer than just a bunch of text. Have you thought about putting together a collection of 10-15 photographs of your people group and country scenes, mixed with some facts or prayer guides to give away to your prayer supporters.
People like to put a face with the person for whom they are praying.
Have a good and concise selection of photos to show people on your next mobilization trip. Und, und, und as the Germans say. The possibilities go on and on. They gadget freaks are hoping I'll say you must. However, not so.
