Hi guys,

I'm dealing with a strange problem. 

I created an HTML signature and it works perfectly on Outlook ( PC 2007/2010/2013) but not so well on mac in Outlook 2011.

If a send an email with text the signature comes up perfectly but if I attach other documents the logo disappear and there's just a red cross.

I noticed that in Outlook (PC) block automatically the incoming images (from Mac) and you need to click trust every time,  but if you send an HTML signature PC to PC everything is good.

Here my signature

Do you know how to resolve?

Thanks a lot!
