function _img_assist_get_thumbnail in Image Assist 5.3

Same name and namespace in other branches

1. 5 img_assist.module \_img_assist_get_thumbnail()
2. 5.2 img_assist.module \_img_assist_get_thumbnail()
3. 6.2 img_assist.module \_img_assist_get_thumbnail()
4. 6 img_assist.module \_img_assist_get_thumbnail()

Attach the thumbnail metadata to the image object.

Unfortunately we have to query the database since the thumbnail can be named something entirely different from the original image.
