If you have D7 configured with an applogo.bmp in your D7Config directory, you’ll notice that logo is now appearing on the new HTML Info Report.
The deal is this, if you have a full size company graphic you would rather display there, simply get a PNG, JPG, BMP, or GIF of ANY SIZE, place in the D7Config directory, and name it “reportlogo” e.g. reportlogo.png
That’s it! The next time you generate a report you’ll have your full size custom graphic in the header!
