Images not displaying in outlook

Hi,

I recently started blogging and have successfully installed feedburner for email subscriptions. The problem is that sometimes images from my blog do not show up in outlook. When I receive emails from other sites with images I am often given the option of “having trouble viewing your email, click here.” I can then view the email and the images properly in my browser. I haven’t been able to find directions on how I can add a “view this email in your browser” option for my subscribers and am hoping someone could please help me with this.

Many thanks, Wendy
