You know on some sites when you're asked to upload, say, an avatar, you click on the button, select your file, then hit OK, but before you Submit the page (as in, no record is created/updated), a little preview of the image shows up?
How would I accomplish this using Paperclip for Rails?
Bonus points for anyone who can point me towards a tutorial or something that might tell me how to do a Javascript crop on the image before saving the record.
I haven't been able to find much on Google on the subject... thanks for the help!
