basically it's just a matter of editing a picture in a photo/image editor (and don't freak and run out and get photoshop; i use a cheapo program that comes free with my computer for all my graphics, sigs, avatars, skins, map textures etc.)
essentially you
- start with a blank project about 125 (h) by 400 (w)
add an image(s) you like or create your own
add some text to it for your name
save it as .jpg, or .gif
host it on a image hosting site (recomend photobucket.com , it's free)
edit: i edited your sig down to 150x400 (if you want to use it , i just ask you host it on your own server as all my servers are piled up with everyone else's sigs and avatars from other MBs) just right click on the image, go to properties and copy the http to your sig code
