Creating custom splash screens?

[XCypserX]

What type of file is the main image of a splash screen? Is it .gif? What else would the .zip have to include? Do i have to name it something specific?

It's a single RAW file, saved as initlogo.rle. You then compress it and save it as RGB565 or RGB8888 file (depending on your phone).

That's the easy part

You have to extract and unpack the boot.img, add your initlogo.rle file, then repack.
