How do I make a signature image bigger?

[Casual Scribbles]

As the title says, I put an image in my signature. The only problem is, it's really tiny, and I want it big enough that people can actually see it with good quality instead of the wierd way it renders at that size. Does anyone know how I make it bigger? I tried adding numbers between the two codes, but that didn't work.

since your image has anti-aliased lines, it won't look good any way you resize it. if i resize it normally, it comes out blurry and ugly, and by using nearest neighbor, the pixels are blown up, which is also pretty ugly. if you're willing to wait a few hours, i can see what i can do

Not sure if this will help you, but the full size / original version is here.
