I'm sure there is a better way from within Mathematica, but I just copy and
paste into iPhotoExpress, an image editing program which allows me to
specify the image size and resolution of the 'incoming' bitmap. The
Microsoft PhotoEditor and Paint programs don't offer the same user control.

For plots, this works fine, allowing me to edit them and import them into
Word docs or Powerpoint presentations. I have less luck with bitmap formulae
though, since they are too jagged for use. For some reason, the windows
metafile format looks beautiful on my PC and prints publication quality, but
is a garbled mess when transported or emailed to another machine, even if
the Mathematica fonts are available on the other machine. WRI tells me the
problem is with the Word graphic filter, and I'm not sure how to work around
this annoying problem.
