You can use it for more that creating images for your blogs. You can sketch and focus on part of an image… Those are things I haven’t gotten to yet. What I’ve used it for is to find an image I’d like to use, create a screen shot, then edit it in Napkin.
The very best part of Napkin? You can literally drag from a png button and create a png file. This file type is compatible with WordPress. Because of this, it’s easier than ever to bring an image into my posts. In fact, I have had to restrain myself!
Napkin is a Mac app that’s definitely worth checking out!
