Attachment_fu: save to a default format

Hi, would anyone have any advices on the next?

I allow users to upload images to my app. I’m using attachment_fu and
There’s two things that I’d like to do:

1- No matter what format the original file is I’d like to save it in jgp
2- I want to keep all images limited to say 1000px width, so resize if
they are bigger.

Is there a way to do that without much hassle?


Resizing is a basic feature, take a look at the README. Format
transformation, on the other hand, is more difficult and is not a
known feature of attachemnt_fu…

Cheers, Sazima
