I would be willing to do that. If anyone has suggestions on changes that should be put in first would like to hear them.

Also, the following in model for validation: validates_attachment_presence :myimg (optional image type validation) validates_attachment_content_type :myimg, :content_type => 'image/ jpeg' Cheers, Jet On Sep 18, 1:22 pm, Brett Nelson <[email protected]> wrote: > That would make for a great recipe onhttp://cookbook.hobocentral.net/ > > On Sep 18, 10:51 am, blueHandTalking <[email protected]> wrote: > > > Here is one way of getting Paperclip to do a simulated Ajax upload, > > and also displaying uploaded image in the current page.
