Re: Slugger pic

Marge, Thanks for the info
I reduced the scale of the original photo so I could post a reasonably sized
file for viewing.
The original is a jpg - which is all my camera will do - but it is 1600 x
1200 pixels, 24 bits per pixel, 387kb.  It took me awhile to find a program
on my computer that would tell me its resolution, but eventually found that
it is indeed 72 dpi.

For file sharing I do use jpg or gif and for printing, usually tif images.
I had intended to convert the original jpg file to a tif as an additional
file so that the photolab would have a choice if they preferred certain
types of images for printing, though I don't know whether the conversion
would have any adverse affect.  Changing the 387kb jpg to a tif creates a
larger file:  5,635 kb, also 72 dpi.
