Hi. I can help you to get the image in your signature. I've done this in the past as well. You need somewhere to store your signature image, a public URL such as dropbox or photobucket maybe, or if you have your own web hosting you can keep your image file there. Chat with me a bit so we can sort that part out first.
I have 10+ years in the IT Industry including two Microsoft Professional Certs. You can see from my profile I'm a 100% professional and trusted freelancer with an excellent reputation. Looking forward to hearing back from you. Regards, Kenny.
