Rene, so far, you can link to a layout and use hyperlink, like THIS for Ann’s layout, by using the hyperlink icon in the toolbar above.
Another way is to embed it by hotlinking to the gallery, in which case you use the image icon. In order to embed, you would go to the gallery, right-click on the full-size image, select Copy image address, and come back to the thread and use that link as the source for the image.
I will definitely have tutorials on how to do all that.
