Hi guys.
No Idea why but I keep getting this message everytime I try and use an uploaded picture as my sig 'It was not possible to determine the dimensions of the image. Please verify that the URL you entered is correct.'
the URL is this http://s3.postimg.org/acg70sucz/TURN_Sig1.png
some help with this would be great as I'm sure its just me being a bit divvy.
