I am trying to post a question and include a sketch. I wrote my text, then did a copy and paste of the sketch to insert it below the text. When I hit post I got this message: " Your post is 508772 characters too long, posts can be up to 21800 characters. Please make it a little shorter and try again."

I certainly do not have over 500,000 thousand characters, that would be like a book!? I am doing something wrong. I've seen sketches and even photos in many of the postings. How does one do that? Thanks.
