Open badge links on iPhone

I have created a signiture within Mail on my MBP. In it includes two "badges" (Facebook and YouTube) with links to the respective pages for my company. When I send myself an email to test the badges, it works great on my MBP. On my iPhone, however, it gives me the option to "copy" or "save image." Is there a way I can change the signature to make it open properly on a computer and mobile platform?
