Re: Downloading thumbnails and replacing them with full images

+1 for easy-thumbnails.  We use it and it works great.  Allows
the user to upload images, optionally crop them during the
upload, manages the full-size and thumbnail files on the file
system with their names in the DB, etc.  All automatic and all
easy.

  I have a django app that downloads 100's of images. To increase the  performance, I want to change it so that it downloads thumbnails, and  when the user clicks on one then download the full image.    I'm sure I can come up with something on my own (send an ajax request  on click, etc.) but I was wondering if anyone has already done  something like this and knew of any packages or can give any hints or  advice.  

    My suggestion - look into easy-thumbnails:    http://easy-thumbnails.readthedocs.org/en/latest/index.html    It's an augmentation of Django's ImageField that allows you to store a  "single" image in your model, but also specify policies for how thumbnails  of any image will be generated (in multiple sizes, if needed). The field  will then automatically generate those thumbnails (either on upload, on  demand on download, or in a background process, depending on how you  configure it), and provide an easy way to find the media URL for each  thumbnail (as well as the original).  

  Thanks very much for the reply Russell. Before I got your message I  found SuperBox which seems to be working for me. But I will keep  easy-thumbnails in mind for the future.    -larry
