I tried, but it probably required you save your picture on a image hosting website...
So, you need to download & edit the images to approx 250pixels by approx 130pixels - in that range anyway. Then upload to an image host. If you are just linking from an online source, you have no way of editing the sizing to make it "right"Thanks Mark,
I'm not sure you can see the pics... or just the link!
Also, I can't seen my signature until it is posted. So no idea of the size of position of the pics.
