The generic option never comes up in that limited search for the moving of images.
This is how I do it: click on the blue underlined Datura genus name in the entry and from there you'll see the generic entry at the top of the list. Click on it and then copy the Plant ID #. You can find it on the blue left side section, right above the blue 'add this plant to your list' button or you can also find it in the URL address. Paste it into your move search box.
