I use CarrierWave to upload user's pictures. my PictureUploader class have 3 version (large, small, thumb).
Now i want to add an article model then make possibility to add an image to article.
what is the best way : create a new uploader for articles ? or just use the existing picture uploader ? if so how to add conditions to say for example : large, small and thumb are just for user model, and "other_version" is for article model
