Hi MIchael, Nicolas

During the last years I added two experimantal   tools for images on
OpenJUMP, available on the standard Affine transformation one:

1)
if the image is loaded via Sextante Raster Image (File>Open>Sextante..)
Tools>Warp>Affine transformation (from warping vectors).
Note that this requires at maximun 3 warping vectors on the view
(Tools<Warp>Warpimg to get the tool to draw warping vectors)

2)
if the image is loaded  via Referenced Image or similar (File>Open>File)
Tools>Warp>Affine Transformation (from parameters)
At the end of the dialog there is a check box "Force affine transformation
of image". If it is checked the affine transformation acts also on the
bufferedimage (and not only on the geometry). The option "Resize image to
half size" should help if the process takes too much time (and too much CPU)
I wrote a small tutorial here:
http://ojwiki.soldin.de/index.php?title=Warp#Applying_an_affine_transformation_to_an_image_layer

Both methods work made only affine trasformation.
And they create new GeoTIFF image files rather then "write/rewrite" a world
file.
Rewriting a world file rather then rewrite the all image should be
preferible and "less memory consuming". Unfortunatelly OpenJUMP still
cannot read and use the rotation/skewing lines on a worldfile.

Both methods should work if the image is not huge. There is no way to
control possible errors
