One more tidbit about projecting images using PowerPoint: A number of years ago Scott Chytil wrote a very useful freeware application called PPTImport. It's a Windows utility that automates the process of inserting bitmap images into a PowerPoint presentation.
He later ceased development of the software and took down its download site. Over the years people have continued to inquire about PPTImport, however, so just today he has once again made it available from his present Web site on an "as is" basis. If you are interested, you can now find PPTImport at: http://www.chytilphoto.com/pptimport/pptimport.asp George George Helfand Account Manager Luna Imaging, Inc. 2702 Media Center Drive Los Angeles, CA 90065-1733 Voice 800-452-LUNA (5862) Voice 323-908-1400 Fax 323-221-2846 Cell 805-905-9562 E-mail ghelfand at luna-img.com Please visit our Web site at www.LunaImaging.com > Date: Wed, 01 Aug 2007 09:38:05 -0400 > From: "Deborah Wythe" <deborahwythe at hotmail.com> > Subject: [MCN-L] DM SIG: digital projectors > To: mcn-l at mcn.edu > Message-ID: <BAY121-F2309E37C9289A0CCA75352CFE80 at phx.gbl> > Content-Type: text/plain; format=flowed > > We've been having some discussions about the resolution of digital > projectors and the optimum size of images for projection.
