Graphics help

[Jools33]

Hi,
I was wondering if anyone would be kind enough to offer me some help with improving a graphic image that I have.
The image is a heraldic family crest but the quality is exceedingly poor & I haven't got a clue how to improve it, but a friend of mine suggested that I should post a request here.
I have tried loading the image to here but I get a 407 error !
Thanks

Ah, I've managed to upload the image now. You will see how poor the quality is, the other thing is that the black background needs to be changed to white so that the shield is clearer.
Thanks

Shouldn't be a problem. Will take a look in the next day or so.

Thanks very much, I really appreciate your help

I've had a go as I had 5 minutes. Sysman might do a much better job than I though. I didn't read the 'white background' bit, sorry but IMHO, it looks better in black anyway.

I have been at home today feeling like sh1t so I had a go to cheer myself up...

Hi,
That's absolutely amazing, thanks very much for your time. Could you tell me what program you used to do it, I would love to learn to be able to do this myself?
