# Choose what kind of storage to use for this uploader:
# storage :fog
# Override the directory where uploaded files will be stored.
# This is a sensible default for uploaders that are meant to be mounted:

# # asset_path("fallback/" + [version_name, "default.png"].compact.join('_'))

# process :scale => [200, 300]

# version :thumb do
# process :resize_to_fit => [80, 80]

# %w(jpg jpeg gif png)
# end
# Override the filename of the uploaded files:
# Avoid using model.id or version_name here, see uploader/store.rb for details.
