image resolution for conference presentation/reading

[William Nickell]

Dear Deborah,

You can pretty much go by what you see on your screen.  If it looks  
sharp to you on your screen, it should look clear when projected.      
Maybe someone else can provide a higher resolution answer than that,  
but it is a good general principle.

And you can certainly use PowerPoint to project jpg and gif images,  
if you haven't done that before.
