If somebody has more or better information on this, I'd love to hear
it but this is how it is as far as I know and have experienced.

First off, DPI is not a function within an image, it is a function
of output and is governed by a combination of the programme doing
the output and the device it is being output to.

So, in conclusion, the DPI of an image is an OUTPUT function - it
is not inherent to the actual image. However, you may see DPI data
stored within the metadata of a file, where it has been stored by
the application used to edit it, because the application has stored
information you have given it to communicate with (usually) the
printer. It serves no other purpose.
Thanks for your explanation. Anyone who agrees with me, must be very
intelligent. :-)
