dear timm,

just below the window where you type in a text, you see a little icon that consists of a picture and a "+" attached to it. just click on it and it will guide you through the selection of images. it will then include the code necessary in your posting. just play around with it and you'll figure it out. it s easy to understand. in later versions this will most likely will be drag and drop. for now this is how it works.

best,
s.
