At least the "Blog this" function at Flickr enables me to post a picture as the previous entry illustrates, however neither changing the theme nor trying to post a small version of a picture instead of a large one works yet when dragging pictures to the blog editor in Flock. Despite this, it still doesn't seem as if it is the blog editor in Flock that is at fault. Here's why I think that. When I create the post, the blog editor saves a copy of the post on my hard disk. I can look at that .html file and in the version on my hard disk, everything looks normal. So it seems that something in the process of publishing the post to WordPress.com strips out a part of the code and therefore causes the picture not to appear. That is true with the two themes I have tried this morning, so I'm not convinced that it is due to the theme I am using. Fortunately, Erwan and Daryl are looking into this problem to see if they can diagnose what is causing it and perhaps fix that.
I'll just have to await further development of the blog editor and the development team's investigation to get a resolution. In the mean time I can work around the problem if I need to post a picture by using Flickr's "Blog this" option.
In the most recent build of the blog editor I am pleased to see that a spell checking option has been added. Heaven knows I need help spelling and while a typo or two isn't something I'm going to stress out about, I do like to spell check my posts before I publish them.
