I just discovered that not all jpegs are made equal. There are jpegs that use the RGB colorspace and others that use the CMYK colorspace. RGB is more common and Internet Explorer can’t handle the CMYK ones: it displays the icon of a broken/unloaded image instead. Another reason to hope it soon fades away but many people still use it.
The solution? If you’re a content producer: create RGB jpegs. If you let people upload pictures on your site: convert pictures to RGB. This is how I did it in my latest Ruby on Rails application which uses Paperclip to handle uploads.
Put this code into lib/paperclip_processors/colorspace.rb (edit: that was for Paperclip 188.8.131.52, check the comments for how to fix than in newer versions)
module Paperclip class Colorspace < Thumbnail def transformation_command " -colorspace RGB " + super end end end
Add this line to your model, as an argument of has_attached_file
:processors => [:colorspace],
That’s it. For a discussion about CMYK images and Internet Explorer read this.
