I created a small BlogEngine.NET extension that allows you to generate a thumbnail image on the fly and display the generated image within the post. The extension also links the thumbnail image to the full sized image so that a user can go directly to the full size image if they wish. Example:
[IMG FILE=Images/walking_small.jpg SIZE=200]
Syntax: "[IMG FILE=Images/walking_small.jpg SIZE=200]"
