image transparency - best program?

[Erica Mc]

We are currently looking at getting new autodesk based software that we can produce drawings in that have .ecw images that can be faded (so the imgaes can come in at real co-ordinates). We currently are using AutoCAD 2009 to produce the drawings then using CivilCAD 3D 2009 to attach and print drawings. The onlt problem is we can't make fade the image. What products are others using for this? We used to convert the images to .jpg and align them in AutoCAD, but this is just a big time waster.
Thanks in advance for your suggestions

AutoCad 2011 has a new feature where you can adjust the transparancy of objects on each layer - including images. I use aerial photos for background images for site development and roadway alignment planning.

Raster Design, will let you convert the images in place and retain the insertion information. and can export a world file for the new format.
