Informatica BDM Access a Local Image

In Informatica BDM I have a java transformation that sends emails containing HTML formatting. At one point in my code I add an image via hyperlink and it works great, the problem is that the server I will be hosting this on has no direct internet access so I need to load this image locally. The trouble is that Informatica seems to have trouble importing images, even if I specify the path where the image is located. Any help in troubleshooting this is greatly appreciated.
