I plan to create jpg files by scanning my old wedding pictures. The files
will be used for PowerPoint presentation. The size of the jpg file will be
10x7.5 inches. What scan resolution should I pick to get a clear and krispy
picture on a big screen by a computer projecter. Should I create 300 dpi or
600 dpi picture file on 10x7.5 inches canvas? Max

Hello

I'm no expert but the following should help:

http://www.pptfaq.com/FAQ00415.htm

Don't forget about the photo album option when you get round to making the
presentation :-) (in 2003 insert->pictue->new photo album)

Along with what has been recommended, here is a good site for scanning
information also. http://www.scantips.com/

Read the linked pages the others have sent you, but the simple rule in your
situation is:

1) Learn the maxiumum resolution your computer projector supports. Usually
this is 1024x768.

2) For images that will be full-slide, scan to that resolution or just a bit
above. Or scan at considerably higher resolution (to PNG or TIFF) then use an
image editing program to downsample them to 1024x768 or whatever you've
determined your projector to be capable of.

3) For smaller images, make them proportionally smaller.

4) Forget dpi. Set your scanner software to work in pixels instead. DPI will
make your head hurt, give you bad breath and make hair grow on your palms. Or
was that "make your palms hurt and hair fall off your head ..."? No matter.
It's bad. Forget it.

Thank you all. Your suggestiond solved all my questions about determining
pixel size for PowerPoint picture insert. I am a Photoshop user, so I won't
have any problem to match pixel size with computer projector's. Max
