Comment 7 for bug 1235569

Discussion also on https://mahara.org/interaction/forum/topic.php?id=6221 with a potential solution by Mike in https://mahara.org/interaction/forum/topic.php?id=6221&offset=10#post26534 -> would need to be checked if it also works for external images and that permissions are respected.

Mike's solution circumvents the need for attaching the image first which would be preferable in my opinion as it would save one step. It should still be possible to attach other files, but images that you want to appear directly in a textbox should not appear in the attachments.
