If an image does not contain location information, you can specify its insertion point and rotation so the image is inserted correctly in relation to other data. You can also adjust the scale so it matches the scale of the other data.
AutoCAD Map 3D saves the insertion-point setting with the drawing. The changes are not saved back to the image file or to the correlation source file. To modify the settings stored in the image file, use an image-editing application such as Autodesk Raster Design. If you modify the original settings in the image, reinsert the image to see the changes in your map.
