Image in Signature is not displayed

Have a couple of sales guys that want to incorporate our logo in their signatures. You can certainly add it in the
signature, and it displays when you add the signature to the email, but the recipients are not seeing the logo. Even if the message
with the logo is sent to another Groupwise user, there is no logo embedded in the signature.

Any thing we are doing wrong? The logo is a jpeg (.jpg) file, and the size is 7KB, we re-sized it to fit for a handheld to make it
as small as possible. I am not finding much in the help on this, unfortunately.

Thanks in advance,
