Can anyone help me with this signature issue. I've been adjusting my signature size on photoshop and is still unable to get it to show up on the fourms. I've gotten one to work but it doesnt show up when i press preview signature any advice would help ty.

 

What size are you attempting to use? Also, what file/image sharing service are you using to host your final picture for you signature? Ensure the link you are using is a DIRECT link to your image and that you are encoding it correctly.
