any way you can try the pictures on the equipment you will be using a day or two before, it will give you a chance to work out any problems. I haven't got any experience with projectors but I do have many years of experience giving programs before large groups. If I could only give you one suggestion it would be to run through what you are going to do ahead of time and work out any problems you may encounter. Finding out that things don't work in the presentation is definitely not the way to go. Run through everything ahead of time. It's like watching a magician do a trick that doesn't work it doesn't empress anyone. Be sure you know what is going to happen ahead of time. Don't get caught off guard.

If you could do a run through with the equipment in the location the presentation will be at during the same time of day would be best.

I put together all the scripts for each of the leaders for my son's Eagle Court of Honor in Boy Scouts. I planned everything to the last detail. All props were checked out and the candles used during the ceremony were all timed so I knew they would not burn out. Everything was gone over so that there would be NO mistakes and the ceremony would be perfect. The only problem was that I didn't run through it in the church where it was going to take place. Everything worked as planned until the air conditioner turned on during the presentation and and blew directly on the candles causing them to burn several times faster than normal and caught the holders on fire. The point of the story is that if you don't check this out ahead of time in the same location you might find something you didn't plan on either such as a light problem that may mess up the projected image. It makes a big difference when you know everything will work right ahead of time. Good luck!!
