Aha, ok I see. Seaside doesn't save the uploaded file anywhere
automatically, that's up to the developer to decide where to put it.
Maybe you want to save it to the file-system, maybe you want it in a
database, maybe you want to mail it somewhere, ... it is up to you.

Yeah, try something like (assuming that file is an instance of WAFile):

stream := FileDirectory default fileNamed: file fileName.
[ stream binary; nextPutAll: file contents ]
   ensure: [ stream close ]

Then you have stored your file in the directory with your image.
Probably you should change 'FileDirectory default' to a different
subdirectory, to avoid accidental overriding of your image.

Cheers,
Lukas
