As it is now, you can enter a url to insert an image into your drag & drop editor. But this does not work directly from your website even though you have a landingpage where the metatag defines where the image and text is on the site. You have to open the image in a new window, and then use this url. It would be much easier if you could just use the link for the landingsite.

Then the link would also be correct for the image, as you want your recipient to end on the landingsite and not just on the image.

If you implement the this, the same option could be done for text - as a number of lines could also be inserted via URL, if the metatag on the website indicates where the text starts.
