I think I've found a bug in Word 2007.

If you create an image with a transparent background (e.g. in Macromedia
Fireworks or another Graphics package) and then copy and paste it (or save as
an image with mattee set to transparent) into word 2007 BETA 2 it displays
the image with a white background and I cannot get rid of it. I can't find
the tool from 2003 called Set Transparent Image Color. The same applies with
inserting the image.

However, If I do the same in Excel or Publisher 2007 it works fine, and the
image imports with a transparent background so it can be neatly positioned
over the top of over images.

Any ideas?
