Your signature looked like it had a bit of a broken link to a Google Images thing, so I'm pretty sure I fixed up the problem for you and put in the image you were referencing, heh. If I didn't do the right thing, then just let me know!
It's not big image-wise, considering what I've been working with the past few days (images up to the size of A4!) but for a forum signature, yeah it kinda is a little too large. Good to see its all cleared up though!
