This article describes how to create custom background images for the PGP BootGuard login screen using GIMP.

If you are using PGP Desktop in a PGP Universal Server-managed environment, an administrator can customize the PGP Whole Disk Encryption BootGuard screen to include additional text or a custom image such as your organization's logo.

Custom background images created for the PGP BootGuard screen must meet the following specifications:


  • XPM files only.

  • Image size of 640 by 480.

  • Palette of 15 colors only, including black (one color is reserved for fonts). You do not have to use all 15 colors in the image.

  • 8-bit RGB only (cannot be 16-bit RGB). You can verify you are using 8 bit by looking at the XPM header using a text editor: 8-bit values appear as #285A83 (one hex triplet), 16-bit values appear as #28285A5A8383 (two hex triplets).

This article details how to use GIMP to create a customized PGP BootGuard image. GIMP is a freely distributed image/photo editing software.
