Revit 9 now allows rotation of imported raster images using the ROTATE command. Just pick the image and use the ROTATE command options. You can simply type in a precise angle in the options bar. You can also pick a base point and pick another point that rotates the image.
Remember, Revit's ROTATE command displays a rotation icon that represents the default base point. This icon can be dragged to a new location on or near the object being rotated. I found I could also "snap" reference planes to the endpoints of a raster image frame to help rotate images to match the angle of the reference plane..
Prior to Revit 9, the ROTATE command could only rotate raster images in 90 degree increments inside Revit. The ROTATE command could also be used to flip images horizontally or vertically.
If an image needed to be rotated other than 90 degrees, it had to be done in an imaging software prior to importing the image into Revit. I usually used the
Microsoft Office Picture Manager which came with my Microsoft Office. The Picture Manager has a PICTURE pulldown menu that allows you to rotate and resize a raster image. This software is located in the
