Cant add signature to live mail without error

I am new to "live mail" so forgive my inexperience. I have used Outlook 2013 and 2010 and on and one before.

I need to use a signature with a graphic logo. I follow the Windows steps for making a signature and when I attempt

to begin a new email I get the following error.

     "Warning your signature file is too large. It has been truncated, please make the file smaller."

I've tried the same jpgs I used in the other windows email client I mentioned. I get the same error. Please help
