Can't use HTML Signature from Outlook

Hi - I have been using a signature in Outlook that has HTML elements and an image that links to our website (as well as a FB button etc.). In EM Client the signature displays fine on old emails. If I attempt to copy and past the signature into EM Clients signature settings the image breaks every time. I tried to copy+paste it into a blank email and the image link also broke. Anyone know how to fix this?
