Resize uploaded image file without creating temp file?

through them, each time saving a new image object resized to the correct
geometry. I know that file column does similar stuff, but I would prefer
to have a separate database row

file_column and Thumbnails
I see that the SVN version of the excellent file_column plug-in can create
thumbnails using the url_for_image_column helper.
This uses Rmagick to create the thumbnail... Quick question...
Let''s say the file is a TIFF image - can the helper create a JPG version of
the thumbnail for display in the browser?
Curious if the plug-in can handle that transform with some creative use of
the
