Yesterday I saw a post about changing the grub and bootsplash images and I rememberd that some time ago I had the intention of making a script to test different images.
Gathering ideas from Joble, Sproggy and all the great people around here, I wrote the following script.
It's ugly, I have no idea of why it does what it does, but it works quite well (At least, I tested it with several images both in mys system and in a vbox install and it worked).
It gives you the option to change both images or restore the ones you backed up.
It has three main problems:
1) If you cancel in the middle of the script, I don't know what the hell happens.
2) It only works if you have the minime default theme enabled for both images. (Which obviously means that it won't work outside PCLinuxOS)
3) It was written by someone who doesn't have a clue as to what all those strange symbols in the script mean.
If anyone could throw in some ideas, corrections, etc., it could become a little better.
EDIT: 2nd version:
EDIT2: 3rd version (this morning I came across the way to make the cancel button in the dialogs actually cancel)
