Now that I know how to insert a picture in the text body of a post (and not as an attachement) and beacuse Helen has asked me to share the knowledge here are the steps you can follow to do it. Once your message has been written follow these steps:
1- Copy the URL of the picture (and you can do that by simply right clicking on the picture and choosing copy URL).
2- Click on "Insert image" icon (you will find it under the smilies drop menu)
3- Paste your picture's URL in the pop-up window.
In theory you are done. The problem I had was that part of the URL is not required...actually delete anything after ".jpg".
As an example this is one URL : "http://api.photoshop.com/v1.0/accounts/a71cd8db24784f44b779cd99d2bf4097/assets/d83f4411bb044f53915460f3987369c5/renditions/1024.jpg?md=1304516613000
" I had to delete everything after ".jpg" witch is "?md=1304516613000
" so you end up with "http://api.photoshop.com/v1.0/accounts/a71cd8db24784f44b779cd99d2bf4097/assets/d83f4411bb044f53915460f3987369c5/renditions/1024.jpg
" and if you paste it in the "insert image " icon like this you end up with
If I can do it, I'm sure you can.
