Great post, thanks. I especially liked learning about StringIO as I didn't know about it before now.

I updated this post. I was thinking the uploaded file was deleted after using it, but I just needed to reset the file. Django's InMemoryUploadedFile uses StringIO. Doing file.seek(0)
will reset the StringIO file to be ready to create another thumbnail.

I'm glad this helped. That was the hardest part to figure out. I didn't want to create a temporary file on the file system and StringIO wasn't the first thing I tried.

Thank you for the StringIO tip, it saved my time :-)

Thanks for the link. I will probably check that out since I know I will want more features at some point.

I'm all for writing a little code to understand a library like PIL. It's worth noting sorl-thumbnail (http://code.google.com/p/sorl-thumbnail/), however, as a django app that solves just this problem... It can do a lot of things but at the simplest level you can just use a template tag to specify the thumbnail size and thumbnails are generated and cached for future use. A very nice app...

I'll probably stick with my method since it gets the processing done initially and avoids the case where many images all need to be resized on a single page load.

Although, having a filter to do that will be convenient if you change your mind on the thumbnail size.

Take a look at this snippets:

Thumbnails are generated in a lazy way. I like the idea.

I hope it helps you out when you need it. I just started learning django and python when trying to figure this out and that is probably why it took me a while.

I am doing a small project in Django (I'm a Python newbie, learning as I go). I initially wanted to deal with thumbnails, but finally skipped it, since was not really relevant to the project. But I'll definitely try this when I start working on improvements.

Thanks for sharing! :)
