It is no good just saying you cannot display it and you get some
‘decode stuff’. Show us the code you have written that you think
should display the picture and whatever is shown on screen where the
image should be displayed. First have a look at the html being
generated (View > Page Source or similar in your browser) and make
sure that the html being generated is what you expect. I would expect
you to be using image_tag to show the image.

Is this a separate question? If so I would advise just having one
question in a post, otherwise the answers to the two questions will
get mixed up. Again though it is no good just saying you cannot run
the server, otherwise the only reply you will get is that you are
doing something wrong. Tell us the error message when you run the
server.

That’s just dumping the raw data into the page. Your browser won’t know
that the data represents an image unless there is an img tag, whose src
attribute points at an action in your app that will send back the data
comprising the image. You might also consider embedding the images
inline via a data: url

Here’s how I display images with paperclip:
<% if items.picture.url(:medium) =~ /missing.png/ %>
<%= link_to image_tag( items.picture.url,:size =>
‘300x300’, :border=> 0), items.picture.url, :target => ‘_blank’ %>
<% else %>
<%= link_to image_tag( items.picture.url(:medium), :border=> 0),
items.picture.url, :target => ‘_blank’ %>
<% end %>

Notice the image tag - items.picture.url not the base object.

Hope this helps.
