Certainly seems complicated to me. And I do it so infrequently that I have to find a host again and relearn the process. There are a lot of questions that I answer that could be really clarified with a small diagram or picture, but I hesitate to include them when it is going to require such convoluted effort. Even with a cable connection it still requires time to open a hosting web site and store the pic there. And in the process of opening another page hope you didn't inadvertently click away from the "Post" composition page and loose everything you have written to that point.

Clicking on the "add image" button and uploading from the computer would sure improve the communication process.
