You don't". Inches is an "artificial construct" and is determined solely
by the setting the "photo" is being viewed in. The picture itself is X
pixels by Y pixels and that is what you are "adjusting". For instance if
the picture is 800 pixels wide and 600 pixels high and you use a printer
and print actual size at 600 dpi. the picture will turn out 1 inch high
by 1.3 inches wide, but on a monitor set at 800x600 resolution it would
fill the whole screen regardless if the monitor was a 14" laptop or a
21" desktop.

Bob,
Sorry but you're misinformed DPI and Pixel Resolution are not the same or even
necessarily related. See these references for more information:
http://desktoppub.about.com/cs/intermediate/a/meas_resolution.htm or
http://graphicssoft.about.com/library/glossary/bldefdpi.htm

To the OP, Irfanview, free from www.irfanview.com, will allow you to
resize/resample a photo easily in either inches or pixels.

HTH,
John

Sorry but, as I said and I quote from the link you kindly provided,

"In practice, SPI and PPI are often used interchangeably. DPI is
frequently used in place of one or both terms. However, even if you call
it DPI, remember that each dot or "unit of measure" behaves differently
depending on whether it is a scanner (or scanned image), a monitor (or
on-screen image), or a printer (or printed image)."

Now I know why politicians get so pissed about being quoted out of context.
Here's the operative quote:
DPU does not correspond directly with PPI because a printer may put down
several dots to reproduce one pixel. This is because printers use a limited
number of colored inks to reproduce an image consisting of millions of colors.
The higher a printer's DPI, the smoother your printed image will appear,
provided you have a suitable amount of image resolution (ppi).

Today's photo-quality ink jet printers have DPI resolution in the thousands
(1200 to 4800 dpi). They will give you acceptable quality photo prints of
images with 140-200 ppi resolution, and high quality prints of images with
200-300 ppi resolution.

The term DPI is often used interchangably with PPI, causing a lot of confusion,
however, DPI refers to the resolution of the printing device, where PPI refers
to the resolution of the image itself.

Cheers,
John
