Render RTF with images in line

[Daniel Castillo]

Hello there, 

I'm having an issue trying to convert RTF to HTML in order to display on frontend side. When the RTF includes an image in the message body, I'm seeing that the format of the image is wmf (window media file) but I'm trying to convert the wmf image to common image format (png, jpg, etc.) but I can't. 

My question is: is wmf the correct format you are encoding the images?

Thank you.
