+1 for sorl. I have been using it for a while now with no significant problems, and has made thumbnail generation a non-issue. Sorry for the slightly off-topic statement here, but since we're talking about Sorl :) - the one problem I've had is this: In general, I want images to be resized in the format the user uploads them - i.e. if a user uploads a PNG, I want the thumbnail to be a PNG, and if the user uploads a JPEG, I want the thumbnail to be a JPEG. It seems a bit silly, but I have not found a way to do this - I set an option in settings.py for THUMBNAIL_FORMAT = "PNG", and then all the thumbnails are PNG, which is non-optimal. And if I set the format to JPEG, it will take uploaded PNGs with transparencies and convert them to JPEGs without transparency, which is, again, unacceptable .. I had looked around a fair bit in the docs, etc. but did not find a way to specify something like "keep format of uploaded image" - this was some time ago, though, so I'll check again - if anyone has dealt with this, though, would love to know how :) Cheers, Sanjay > https://github.com/sorl/sorl-thumbnail > > > On Saturday, February 2, 2013 12:33:36 PM UTC-8, nYmo wrote: >> >> Hi all, >> I'm new to django and also python but have already some programming >> experience.
