Image Attach with Image Assist

If anyone is interested, I've been lately playing with the image_assist module because it works well for multiple images in an article, similar to the system in our old CMS. However, image_assist doesn't make any images available for teasers through node->iid references as the module uses a different table, img_assist_map. I've made some changes to the image_attach module so that it plays nice with img_assist if available, and the first image in img_assist for that article will be available for teaser thumbnails, etc.
It's probably far from perfect, but seems to work for me when I use it with some custom view plugins.

It's set to only work for 'story' node types, and this would probably be best in an admin dialog. It's not seamless, for example, the views module seems to not find the image properly.
