For one thing, you have to think through what you are asking. If we
might think of images having some absolute dimensions of themselves, the
DPI would be unsuitable for most purposes, so you must decide what DPI
you wish to have for your image, then consider how to center.

Let's imagine you wish to import an image to a frame of a certain size,
at a certain scaling, then center it.

Make your frame, import the image, then adjust scaling as desired (you
will need to use Free Scaling of course), but leave the image with its
X-Pos, Y-Pos (as shown in the Image tab of Properties) at 0, 0. Now open
the Multiple Duplicate dialog, use the By Number of Copies tab, select 1
copy, select Shift Created Items By, and leave the Horizontal and
Vertical Shifts at 0 each, then click OK. Your copy will be right over
Image -- this size of this frame will be the size of the image at the
scaling you have chosen. Now push this down a level below the original.

In X,Y,Z you can get the Width and Height of this adjusted frame. let's
imagine these values are 897.76 and 602.64 pts. Let's imagine that the
width and height of the original are 398.54 and 314.42. Now, select your
original, small frame and go to Image tab of Properties, and in the
X-Pos spinbox enter -843.21/2 + 398.54/2, and in the Y-Pos -602.64/2 +
314.42/2. This will center the middle of the image horizontally and
vertically with the original frame.

This description may sound complicated but conceptually it's rather
simple (I think) -- you are shifting the midpoint of the image to the
upper left of the original frame, then adding half the width and height
of the frame.

Again, I would repeat that this kind of operation seems unlikely to be
in much use once you consider the scaling variability.
