How do I upload an animated signature?

[Mayor Peyton]

So I had a signature custom-made for me and I cannot figure out how to upload it. Every time I click 'upload', it brings me to a screen that says I can't upload an animated signature. I have seen so many animated signatures, and need help on how to upload them. Thanks c:

Go to Imgur. Upload your image, and then use
