Importing Photoshop Edited Images to Scale

[rhaskell]

I'm using AutoCAD 2011, we do a lot of work editing images in Photoshop CS5 then bringing them into CAD. However, in this version of CAD, any image (jpeg, pdf, tiff, etc) that has been edited and saved out of Photoshop no longer comes in to scale in CAD. This never was the case in the past. The images remain perfectly at scale, until you save them in Photoshop and it loses all scale (in CAD only - still to scale in InDesign). Has anyone ever encountered this? Is it possible the upgrade to Photoshop CS5 changed something? It's extremely important that we bring in drawings to scale and this currently doesn't seem possible. Please help!

Can you try and provide a heck of a lot more details? Remember, we can't see what you are doing from way over here.
basics:
- Method of importing the image in AutoCAD? And did you try to use another method?
- Scale in Photoshop/InDesign means what to the rest of us AutoCAD users?
- How are you measuring the out-of-scaleness in AutoCAD?
- If you printed the image to paper, is it also out-of-scale?
