Good Fileupload plugins for rails

Would appreciate i开发者_Go百科nputs on the best file upload plugins with support of atleast following:

1. Resizing images.
2. Flexibility of specifying the place of storage.
3. Nice AJAX progress bar integration.
4. Multifile uploading facility.

Thanks.

You won't find a rails plugin that does all of that.
But with two ones, you can have what you're looking for.

Take a look at paperclip, which manages file upload from the server side (in ruby), the place where you want to put the file and the resizing of the images.

And take a look at swfupload (and possibly the rails plugin that goes with it, swfupload_fu) to have the client side and manage multiple file uploading.
