ruby on rails - Need assistance choosing a image management gem -

-

i interested in building rails based system handling display , organization of large amounts of photos. sort of flickr smaller. each photo have metadata associated it. photos shown in selectable list , grid view. nice able load images needed (as speed things up).

at moment have test version of database working images loading assets/images directory beginning run slow when displaying several images (200-600 images). due way have view setup. using straight loop display images in both list , grid layouts.

i manually resized thumbnails , medium sized image full sized source image. investigating other resizing methods. advice appreciated here well.

as new handling images way, point me in direction based on experience designing , implementing flickr?

i investigating following tools:

  1. paperclip
  2. attachment_fu
  3. carrierwave

i'd go carrierwave anyday. flexible , has lot of useful strategies. generates it's on uploader class , has nifty , self explanatory features such automatic generation of thumbnails (as specified you), blacklisting, formatting image, size constraints etc; can put use.

this railscast ryan bates - http://railscasts.com/episodes/253-carrierwave-file-uploads useful, if haven't seen already.
