thumbnail links for images

Everything in the plugin works fine. Thank you for creating such a helpful plugin. I am trying to display thumbnail link of the images that were uploaded via the plugin. I have no problem displaying the actual image and resizing it. However, I can’t figure out how to dynamically link the thumbnail back to the original image.

I don’t want to use an absolute path to the image because the link will need to dynamically update itself to whichever user’s profile is being viewed.
