The method samoht04 describes is a good one, but we don't really expect you to deliberately delay posting a new chapter just because nobody has posted any comments to help create a gap between posts with pictures. Giving a bit of time for folks to read the chapter is a good idea, just so they don't feel so overwhelmed with updates. However, I've been known to post chapters quickly because I have to write when inspiration hits and once it's written, I always want to go ahead and share it.
I think you'll use good judgement, Seera. If you run into any problems, you can always post them here or even send me a private message.
