Adding watermarks to Crystal Reports

First step is to copy the watermark image to the Page Header section or in any section in which you want to locate your image. 

 If your report is already using the page header, you can add an additional page header by right clicking on the Page Header section and choosing Insert Section Below.

Once you insert the watermark image you may need to re-size it or re position it lower so that it is does not show up at the top (unless that is what you want).

Now go to Report > Section Expert, click on the Page Header (if you created a new section, it will be Page Header b) under Sections and check Underlay Following Sections on the Common tab.

Click OK and go to your report Preview
