This module add a url formatter for image field. Then you can output image url directly.
Most of the code, maybe more than 90%, is just copy from the drupal core. I think it is stable enough.
I have created a content type, and add an image field instance to it, later i use views to export the data of this content type.And i want to output the data,then i could import it into another drupal 7 site with feeds module. What i need is the url of the image field, but i could not export the image url directly. That is why i create this small module.
