The IMAGERES attribute may be used to specify the resolution of images accessed using the FILE element in Dots Per Inch. Used like this:

IMAGERES="dpi"

the resolution defined in IMAGERES is only used when the image file specifies the resolution as 0 or does not specify the resolution at all. For example,

IMAGERES = "100"

is a useful default for most printers. Alternatively, use

IMAGERES="-dpi"

to override resolutions specified in image files and force the IMAGERES value. E.g.

IMAGERES = "-96"

gives good results for viewing an image on-screen.
