Creating a custom boot and splash image

While researching ways to create a custom boot image, so I can provision new systems automatically with a CD or a mounted ISO image, I also learned how to create a custom splash.lss image.

Most web pages out there instruct you to install ancient, obscure giftoppm tools - which you may not have or know how to get. I found out Irfanview (for Windows) easily lets you open and edit JPG or GIF images, rework them, add logos and text and save the result as a PPM file.
Then just scp the .ppm file to Linux and use the ppmtolss16 tool (obtained through 'yum install syslinux') to convert the PPM file to LSS. Build the custom ISO image and you're done!
