I think that you probably want the standard FileField or ImageField described here: http://www.djangoproject.com/documentation/model_api/ These fields do not actually store the file/image in the database, just the name of the file. You need to set MEDIA_ROOT/MEDIA_URL as described in the documentation so that Django knows where to save the file to disk. If for some reason you want to go back from filename to model then you can do a query based on the filename, remembering that the path you are querying for is relative to MEDIA_ROOT. e.g. mymodels.get_object(myfilefield__exact="myimage.jpg") Kieran
