Ok, i've made a sig (thats a first) but i can't upload it the right size. Usually I use image shack but that seems to have out of whack. Is there any other way of uploading sigs?
And while I'm asking for help could you suggest a program for creating sigs n' stuff? Thanks.

You should resize the signature to the correct size, then upload it.

Photoshop is my personal favorite for making sigs. Works very well. I wont go into details, but there are some free alternatives to photoshop also that you can try.
