I’m trying to display an image in a view from MySQL, but I’m not sure
where to put the send_data call.
Any help would be great.

Make a controller that calls send_data when sent the relevant object :id
as a parameter, and make it the image src …
def show_image
o=Object.find(params[:id])
send_data o.jpg, :type=>“image/jpeg”, :disposition=>‘inline’
end
If your Object can store different types of image, don’t call them o.jpg
and make sure you can intuit the correct MIME type … perhaps by
storing that in the object as well …
send_data o.img, :type=>o.mimetype, :disposition=>‘inline’
Then invoke the show_image controller as the src of an image tag,
sending the Object.id as a parameter …
(You should be able to assemble the correct URL with link_to calls)
