I have used an HTML image through Tools, Options, Compose etc but perhaps haven't yet mastered the correct way of doing it. It seemed to work OK but when sending to a Mac, the message would display two signatures, but not on a PC which showed only one. On the Mac, the signature appeared to pick up a background as well as the image itself although did actually show two imagaes that werre identical.

When selecting the 'signature' tab in 'options', there is an option for 'text'or 'file' so thought by checking 'file' I could import my gif but an error message stated it was "not a valid text file" when selecting a new message. Perhaps I should give Bill a call?
