Thanks - my interpretation of this failure in version 7 is a little 
different, though:
ImageScaled[1] seems to behave consistently with Scaled[1] (which is 
officially valid) in versions 7 and 8. But neither Scaled nor 
ImageScaled can be handled by Inset in version 7 when only a single 
length argument is given. This only works in 8, and you're right in that 
this change is not documented.

But at least it's an improvement because it brings more consistency 
(ImageScaled coordinates are already being used the symbolic position 
coordinates such as Center,...)
