Here is my mod for the PMDG 737-800 UFT, Ryanair wallpaper and new icons for the Electronic Flight bag and Performance Tool apps.
The background is made quite dark not to dazzle the eyes during night time.
Don´t forget to backup the Assets folder mentioned below BEFORE you owerwrite the original files!
In case you want to go back to the original background and icons.
INSTALLATION: Copy the content (three files) in folder Ryanair_efb to ...\Community\pmdg-aircraft-738\html_ui\Pages\VCockpit\Instruments\PMDGTablet\pmdg-737-800\Assets
If you want use it for another version of the PMDG 737, just look for Assets folder under your particular version( i.e pmdg-737-700\Assets)
Note: If you only want to use the icons, copy ONLY efb_icon.png and pmdg_logo_icon.png to the Assets folder.
