This plugin implements attachment storage and processing, integrated with ActiveRecord models and Ruby CGI/Rails-style uploads. Image processing operations including a number of different resizing & thumbnailing modes are provided, and the architecture simplifies clean implementation of other types of processing. Errors are carefully handled to minimize the possibility of broken uploads leaving incomplete or corrupt data. RMagick, MiniMagick, and ImageScience image processors are supported. Compatibility ============= Currently tested against Rails 3.2.13 and 3.1.8, on Ruby 1.8.7 and 2.0.0p0. Was also tested compatible with 2.3.14 and 3.0.17.
