[Small changes double file size]

If I open a jpg file and draw a single line just a few pixels long, when I save the file it doubles in size (as in disk space, not pixels). How can I prevent that from happening.

[Feature Req: Add a 'Save ALL' feature to Paint.NET]

Greetings. For my first post, I am a little nervous. I don't want to offend anyone by being seen to infer any unspoken meaning. So, you don't say if you do or do not like the idea of having a Save All option. I notice that the suggestion appears on the board as far back as 4 years. From that, I hope I am safe in infering that at least there were a lot of ideas you liked more than Save All.

Can you say what the likelihood of having that option is in the near future?
