Bump.
If you wanted the sig to have a 160 pixels height, here it is without changing the proportions.
Doesn't look good to me when it's that small though. Didn't know you wanted the sig to be 160px in heights only.
If you just wanted it smaller than the original:
Here it is.
If you wanna change the size and if you have photoshop, just save the image, open it in Photoshop, go to Edit > Image Size and put in the dimensions you want for height or width. Make sure you have the three boxes ticked at the bottom (scale styles, constrain propotions and resample image), that way when you resize it, it won't look squished.
Not sure why there's a white box around the sig after you resized it though, I made it the same colour as the background of this forum. D:
