I was told it couldn't be done... so being me I had to do it anyway. It took a bit of editing so it doesn't look exactly like the original, but it is twice the size of the original. It's not as defined... a bit softer looking. I hope this will do.... it's not perfect... but for a 10 minute job it's not too bad either.
Click to enlarge.... click once to see it bigger... then click the bigger one to get the full size...
