hey, I try to display pics (jpg) from my db but all I get is the "white box". The pic and all of its att look fine in the db.

It goes something like this:

in show.rhtml: <%= image_tag(url_for(:controller => 'upload_controller', :action => "getpicture", :id => @picture.id)) %>

in upload.controller.rb:   def getpicture     @picture = Picture.find(params[:id])     send_data(@picture.data,                     :filename => @picture.name,                     :type => @picture.content_type,                     :disposition => "inline" )   end

somebody has any idea ? thnx.

There is a alternate way to do this.. i once did in that way..

I stored the images under the public folder and saved the path in the db or can do like this,

While accessing u can do like <%= link_to image_tag("#{video.path_to_thumbnail_image}"), video_path(video) %> where path_to_thumbnail_image is a method to display the path of the thumbnail created from the video.

All the best. Ratnavel
