Nice, simple code and works perfectly. Thanks a lot for both the code and the decent guide-through. Nice, simple code and works perfectly.

The fields in the instance which is passed into your callable are filled out in order of declaration, so if your image is defined first, the instance will have EMPTY STRINGS for all other fields and you will get an EMPTY FILENAME.

I've a bunch of these CustomImageField hacks, and I'm just starting to update them, but first needed to get up-to-date on the refactoring stuff. You've really made it easier for me. Thanks alot!

Admin is getting all the field values (including the upload_to path) before saving. Before the first save, there is no id for you to use. In your own views, you get to create the model instance first and then save the image, but not with admin. If there's another field you can use, such as a slug, that's probably the best alternative. Otherwise, you could upload to a temporary path and respond to the post_save signal by moving the image to its proper location. @Kevin Holzer

Do you have any recommendations as to what I should do? I've been playing with this a <em>lot</em>, and I've had no luck. Thank you very much!
