I found this post that is similar to my problem. In my SSRS 2008 report I need to have a image in the header where I need to place a text with an expression inside the image.

Adding the textbox inside an image that is a background image works well, except I also need to export to word. What I read here:
http://msdn.microsoft.com/en-us/library/dd283105.aspx
"Newsletter-style column reports are not rendered in Word. Report body and page background images and colors are not rendered."
So if I can't use background images and need the textbox inside the image, what are my options then?
