There's no way to do this in FO--the page and page region dimensions
must be explicitly specified.

However, you can use a Java XSLT extension to examine your images to get
their intrinsic size and then generate the appropriate page dimensions.
We use the Sun-provided JAI (Java Advanced Imaging) library to do this.

The basic technique is:

import javax.media.jai.JAI;
import javax.media.jai.RenderedOp;

RenderedOp img = JAI.create("fileload", fileName);
// fileName is graphic filename, naturally
height = String.valueOf(img.getHeight());
width = String.valueOf(img.getWidth());
