Sharing your flipcharts with others can be a problem. When students are absent it would be nice for them to be able to view the lesson from home. They do not need all of the cute actions involved with the chart in the classroom, only the information. This can be done in several ways. Here is one way.
Make sure all of the pages in your flipchart have all of the information showing. Then PDF your flipchart. You can use one of the free PDF programs like Primo PDF. Once it is PDF'd you can then upload it to a slidesharing site like http://www.slideshare.net/ . The link to the uploaded file can then be sent to the parents or put on your webpage. The student can then view each page in your flipchart. If you have a blog Slideshare will also give you the code needed to embed the chart into your blog. That is how I put my flipchart "How the West was Promethean'd" into this blog.
