You would need to prepare the picture in an application like Photoshop, making it faded, etc. Save as say a jpeg or png format.
Then in Layout mode, Insert > Picture… and send it to the back. Probably wise to lock the picture so it does not interfere with moving and selecting other objects.
Old thread, but same subject.
Something have changed in FM12. Before I could have a picture in a field, as a backgound. Now I am not able to use neither a field nor a picture file inserted in the layout, as a background. The text doesn't want to be placed on top of the picture, no matter what I do.
What am I doing wrong??
