params[:image]....the actual file is here correct?
If you look at the form, it's probably using a group of file fields
with a name of 'image'. Get params have no concept of arrays, so
this is basically posted like this:
Rails parses fields with names ending in  into an array. So
params[:image] is an array of the images from the file field.
and is that the same as this?
etc... for multiple files?
It's an array... params[:image]
also, what is the purpose for images? cant one just call
Image.create(:uploaded_data => img) inside the block?
Yup. Alex was just showing an example using #each instead of
#collect. #collect will return an array of the created images. With
#each, you have to populate an images array manually.
