I’d like to display an image from the data submitted from a file field  
before it’s written to the database, but I’m having a hard time  
figuring it out. If I put the send\_data function into crop, the image  
displays, but without the layout, but the way it’s set up below, the  
data isn’t being passed to the temporary\_photo display.

Is there a better way to do this? Help!

## The controller

def crop  
@photo = Photo.new( params[:photo] )  
end

def temporary\_photo  
@photo = Photo.new( params[:photo] )  
send\_data(@photo.attachment\_data,  
:filename =\> @photo.filename,  
:type =\> @photo.content\_type,  
:disposition =\> “inline”)  
end

## crop.rhtml

\<%= image\_tag url\_for( :action =\> :temporary\_photo ) %\>

Try this:

\<img src="\<%= url\_for(:controller =\> “your\_conroller”,  
:acion =\> “temporary\_photo2,  
:id =\> @photo\_id %\>” /\>

Works here.
