I've created a few presentations for a laptop (1600x1200). Only to turn up and invariably find the projector is 1024x168 or less. There were no visible problems. The things are designed to be seen from a few meters away It might be worth phoning ahead and finding out the spec. but its not critical. Even if you overcompensate with 300MB tifs, the worst that can happen is a lag between slides. :biggrin:
