I'm having another go at this and have succeeded except for one
remaining question.

My object is to upload a file and make a thumbnail at the same time.

Say I have a table with two fields MainPic and ThumbPic:

1. Upload an image to MainPic field
2. Get the filename which has been given by system
3. Read that file with PIL and make a thumbnail.
4. Save it back to uploads dir with a new filename
5. Save the new filename in the ThumbPic field

I have managed to do all that.

But, how can I get the system to give me the new filename in step 4?

(At the moment I have to make up the filename myself and that doesn't
play nice with downloads).

Thanks,  David
