Has anybody figured out a way to force attachment_fu to regenerate thumbnails? I had some major issues with mini_magick not figuring out the correct image sizes, and I''d like to re-try with rmagick. But, I can''t re-upload all the files.

Jodi,
I had seen that link before posting, and I''m not sure why it
didn''t work
for me the first time around. Of more important info possibly is that
my server had ImageMagick 6.2.4, and it was (randomly) reporting widths
and heights of null, and wasn''t actually resizing the thumbnails.
Upgrading to 6.3.8 fixed this problem. Anyways, here''s my script which
I ran that fixed the data....
Photo.find(:all, :conditions=>["width IS NULL and height IS NULL and
parent_id IS NULL"]).each do |p|
puts "Fixing #{p.filename}"
temp_file = p.create_temp_file
image = MiniMagick::Image.from_blob(temp_file.path)
p.width = image[:width]
p.height = image[:height]
p.save
p.attachment_options[:thumbnails].each { |suffix, size|
p.create_or_update_thumbnail(temp_file, suffix, *size)
}
