I'm trying to put this picture in my signature. I been trying but no luck. Thanx!

 

Just use MSPaint. Go to Image --> Stretch / Skew --> and play with the Vertical / Horizontal percentages.

 

I made two. One with the original aspect ratio, which to fit the sig standards is 201 X 150. I stretched out the other to 350 X 150, but it don't look too good. Post up a pic of the original size one. That would be better to work with than an avatar pic. Preferably at least 800 X 600 if you got it.
